feat(peridot-cli/task-info): fetch and display task details

Browse Source 
given a task ID, fetch its details and display them to a table or to
json with `-o json`. Table view also adds a calculated task duration and
can optionally include the submitter information as well as a link to
logs for the task.

* --no-color - to skip colorizing output
* --L|--logs - include column with link to logs
* --submitter - show submitter
* --no-wait - control whether to wait until a task completes to output
  (table mode)

ASCII Table Writer
=========
[![Build Status](https://travis-ci.org/olekukonko/tablewriter.png?branch=master)](https://travis-ci.org/olekukonko/tablewriter)
[![Total views](https://img.shields.io/sourcegraph/rrc/github.com/olekukonko/tablewriter.svg)](https://sourcegraph.com/github.com/olekukonko/tablewriter)
[![Godoc](https://godoc.org/github.com/olekukonko/tablewriter?status.svg)](https://godoc.org/github.com/olekukonko/tablewriter)
Generate ASCII table on the fly ... Installation is simple as
go get github.com/olekukonko/tablewriter
#### Features
- Automatic Padding
- Support Multiple Lines
- Supports Alignment
- Support Custom Separators
- Automatic Alignment of numbers & percentage
- Write directly to http , file etc via `io.Writer`
- Read directly from CSV file
- Optional row line via `SetRowLine`
- Normalise table header
- Make CSV Headers optional
- Enable or disable table border
- Set custom footer support
- Optional identical cells merging
- Set custom caption
- Optional reflowing of paragraphs in multi-line cells.
#### Example 1 - Basic
```go
data := [][]string{
[]string{"A", "The Good", "500"},
[]string{"B", "The Very very Bad Man", "288"},
[]string{"C", "The Ugly", "120"},
[]string{"D", "The Gopher", "800"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Name", "Sign", "Rating"})
for _, v := range data {
table.Append(v)
}
table.Render() // Send output
```
##### Output 1
```
+------+-----------------------+--------+
| NAME | SIGN | RATING |
+------+-----------------------+--------+
| A | The Good | 500 |
| B | The Very very Bad Man | 288 |
| C | The Ugly | 120 |
| D | The Gopher | 800 |
+------+-----------------------+--------+
```
#### Example 2 - Without Border / Footer / Bulk Append
```go
data := [][]string{
[]string{"1/1/2014", "Domain name", "2233", "$10.98"},
[]string{"1/1/2014", "January Hosting", "2233", "$54.95"},
[]string{"1/4/2014", "February Hosting", "2233", "$51.00"},
[]string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetFooter([]string{"", "", "Total", "$146.93"}) // Add Footer
table.SetBorder(false) // Set Border to false
table.AppendBulk(data) // Add Bulk Data
table.Render()
```
##### Output 2
```
DATE | DESCRIPTION | CV2 | AMOUNT
-----------+--------------------------+-------+----------
1/1/2014 | Domain name | 2233 | $10.98
1/1/2014 | January Hosting | 2233 | $54.95
1/4/2014 | February Hosting | 2233 | $51.00
1/4/2014 | February Extra Bandwidth | 2233 | $30.00
-----------+--------------------------+-------+----------
TOTAL | $146 93
--------+----------
```
#### Example 3 - CSV
```go
table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test_info.csv", true)
table.SetAlignment(tablewriter.ALIGN_LEFT) // Set Alignment
table.Render()
```
##### Output 3
```
+----------+--------------+------+-----+---------+----------------+
| FIELD | TYPE | NULL | KEY | DEFAULT | EXTRA |
+----------+--------------+------+-----+---------+----------------+
| user_id | smallint(5) | NO | PRI | NULL | auto_increment |
| username | varchar(10) | NO | | NULL | |
| password | varchar(100) | NO | | NULL | |
+----------+--------------+------+-----+---------+----------------+
```
#### Example 4 - Custom Separator
```go
table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test.csv", true)
table.SetRowLine(true) // Enable row line
// Change table lines
table.SetCenterSeparator("*")
table.SetColumnSeparator("╪")

#### Example 9 - Set table caption
```go
data := [][]string{
[]string{"A", "The Good", "500"},
[]string{"B", "The Very very Bad Man", "288"},
[]string{"C", "The Ugly", "120"},

table.Render() // Send output
```
Note: Caption text will wrap with total width of rendered table.
##### Output 9
```
+------+-----------------------+--------+

Movie ratings.
```
#### Example 10 - Set NoWhiteSpace and TablePadding option
```go
data := [][]string{
{"node1.example.com", "Ready", "compute", "1.11"},
{"node2.example.com", "Ready", "compute", "1.11"},
{"node3.example.com", "Ready", "compute", "1.11"},
{"node4.example.com", "NotReady", "compute", "1.11"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Name", "Status", "Role", "Version"})
table.SetAutoWrapText(false)
table.SetAutoFormatHeaders(true)
table.SetHeaderAlignment(ALIGN_LEFT)
table.SetAlignment(ALIGN_LEFT)
table.SetCenterSeparator("")
table.SetColumnSeparator("")
table.SetRowSeparator("")
table.SetHeaderLine(false)
table.SetBorder(false)
table.SetTablePadding("\t") // pad with tabs
table.SetNoWhiteSpace(true)
table.AppendBulk(data) // Add Bulk Data
table.Render()
```
##### Output 10
```
NAME STATUS ROLE VERSION
node1.example.com Ready compute 1.11
node2.example.com Ready compute 1.11
node3.example.com Ready compute 1.11
node4.example.com NotReady compute 1.11
```
#### Render table into a string
Instead of rendering the table to `io.Stdout` you can also render it into a string. Go 1.10 introduced the `strings.Builder` type which implements the `io.Writer` interface and can therefore be used for this task. Example:
```go
package main
import (
"strings"
"fmt"
"github.com/olekukonko/tablewriter"
)
func main() {
tableString := &strings.Builder{}
table := tablewriter.NewWriter(tableString)
/*
* Code to fill the table
*/
table.Render()
fmt.Println(tableString.String())
}
```
#### TODO
- ~~Import Directly from CSV~~ - `done`
- ~~Support for `SetFooter`~~ - `done`
- ~~Support for `SetBorder`~~ - `done`
- ~~Support table with uneven rows~~ - `done`
- ~~Support custom alignment~~
- General Improvement & Optimisation
- `NewHTML` Parse table from HTML

// WrapWords splits a list of words into lines with minimal "raggedness",
// treating each rune as one unit, accounting for spc units between adjacent
// words on each line, and attempting to limit lines to lim units. Raggedness
// is the total error over all lines, where error is the square of the
// difference of the length of the line and lim. Too-long lines (which only
// happen when a single word is longer than lim units) have pen penalty units
// added to the error.
