Adds a new err_msg function which is used to:
-echo feedback to the deploy ramdisk console
-keep track of the first error message we hit so
that we can send it along to the baremetal-deploy-helper.
Also, updates our wget request back to baremetal-deploy-helper
to include the first the first error message (if any) as
the 'e' parameter.
The err_msg uses a new simple safe_url_encode function to ensure
we don't send invalid characters in our HTTP post requests.

Adds a new 'troubleshooting' function which encapsulates
the things we might want to do when something bad happens.
Typically this is echo'ing a simple message and launching a
bash shell.
The new troubleshooting function also makes use of a new
'troubleshoot' kernel param which if specific will allow you to
hang the deployment process and interactively debug the deploy_ramdisk
via a bash shell on a console.
Troubleshoot is disabled by default.
Fixes LP Bug #1191043.

Updates our deploy element's init script so that it calls
find_disk in a loop until it returns true (meaning we have a disk).
Previously on some bare metal machines find_disk would return ""
which causes the subsequent iscsi target commands to fail due to
a bad backing store.
This commit also updates the error message when start_iscsi_target
fails to be a bit more accurate as well.
Fixes LP Bug #1190984.

Flavour is overloaded in openstack due to it being used by nova. Element
seems to have the same feeling of combinability without using a term already
in active use in the openstack community.
