2d2b2725bd Remove PluginBase/NodePluginBase class
A majority of the "plugins" aren't implementing the plugin class.
Clearly we need some refactoring of the ideas here.  Remove for
simplicity.

6d0b9abc0f Apply setfiles on all mountpoints
With new block device definition, where content of the image
can be mounted on different partitions, is not enough with
executing setfiles on root directory. Instead of that, expose
all the mountpoints on the image, and apply setfiles on them.

e4e23897a1 Refactor: block-device filesystem creation, mount and fstab
This patch finalizes the block device refactoring.  It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.

Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.

Notes:

 * unmount_dir : modified to only unmount the subdirs mounted by
   mount_proc_sys_dev().  dib-block-device unmounts
   $TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9)

b9c065de28 Remove args from BlockDevice() init
The args agument was only used to find the symbol for the getval
command.  Have the command pass the symbol to find in directly.  We
can therefore remove the args paramater to the BlockDevice() creation.

0d8c4270c0 exec_sudo: check cmd for str, log output and raise exception
To avoid any confusion, commands passed to exec_sudo() should be a
list of "str"s.  Log a message if we see unicode issues.

This also adds a debug trace of all output.  stderr is captured.

This is modified to raise CalledProcessError on failure, like
check_call().  Calls that are ok to fail will need to explicitly catch
and ignore this.

The two calls that we expect to fail are wrapped

We wish to try rolling back if one of these command raises an
exception.  Modify the create handler to initiate rollback on all
exceptions.

91ba21dd6c Set LC_ALL in disk-image-create
It seems that the redhat nodepool job is quite reliably geting a
"floating point" error during centos image build.  This happens after
03-yum-cleanup which is pruning the locales.  This might be a
red-herring, since the logs are full of

  /bin/bash: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)

I think in our recent de-puppetisation of hosts, something might have
changed that is setting LC_ALL=C.UTF-8 for the jenkins user, at least
on Ubuntu.  This is a problem for centos, as it doesn't have C.UTF-8
locale.  I then think using the invalid locale is what leads the the
floating-point error when doing some maths in dib-run-parts to
calculate runtimes.

We are currently overriding LANG, but we really want LC_ALL to ensure
this applies globally.

803d40b0c6 Refactor block_device: passing command line parameters
The original approach was to pass each and every command
line parameter to the block device.  While the block device
functionality gets extended, this is not any longer practical.

Instead of passing in all the parameters separately this patch
collects these in a YAML file that is passed in to the block device
layer.

79d4113cbe pip-and-virtualenv : install python2 & 3, and default to 2
Recent changes in project-config have shown that we leave the system
in an inconsistent state when installing from source.  On fedora, we
will have installed the python2 packages, but then used $DIB_PYTHON to
install python3 pip from source!

This tries to clarify the situation.  As described in the document,
with package installs, we just install the $DIB_PYTHON packaged
versions.

Source installs want to take over the global namespace.  This is the
price you pay for running the latest versions outside package managers
:) The only sane thing seems to be for us to normalise python2 &
python3 versions of pip, setuptools and virtualenv and then hacking
things such that "/usr/bin/pip" and "/usr/bin/virtalenv" remain
defaulted to python2 versions.

Documentation is added

ffd4820d59 Install pip with python interpreter

This means that every time you create a virtualenv, the python

Add an env var DIB_PYTHON that points directly the to interpreter
available during build, for use when running scripts.

f068e6aa6e Fix package-installs-v2 output
The current output for package-installs-v2 is inscrutable [1]

The problem starts with process_output() which is not capturing
stderr.  This means that any stderr output is dislocated from any
stdout output around it.  This is *really* confusing as you get a
bunch of seemingly meaningless stderr output from any calls before you
see any stdout (e.g. in [1] you can see random yum error output that
should have been with the yum call)).  The simplest thing to do is to
redirect stderr to stdout which keeps everything in sync.

This causes a slight problem, however, because pkg-map outputs both
status information and errors on stderr.  To work around this but
maintain compatibility, we add a "--prefix" argument that prepends
mapped packages from pkg-map with a value we can match on.  The
existing status/debug output from pkg-map is low-value; modify the
call so that it will be traced only at higher debug levels (e.g. -x
-x).

The current loop is also calling pkg-map for every package in every
element (this is why in [1] the same message is repeated over and
over).  This is unnecessary; it only needs to pkg-map once for each
element, giving the package list as the arguments.  Create package
lists by element and pass those to pkg-map.

As a cleanup, there is no point in printing e.output if the
process_output fails for the install because we are already tracing
it; i.e. the output, even for failures, is already in the logs.
Printing it again just duplicates the output.

[2] is an extract showing what I feel is a much more understandable
log output for a fairly complex install.
