[RFE] Allow Deployment Agent to Log Information to Ironic Service

[Vladyslav Drok]

Currently, there is no way for a deployment agent to log information back to the service in case of problems.

This proposal is to provide an interface for the deploy agent to provide arbitrary log information to the service, to be surfaced at least in a service log file, or perhaps surfaced even as far up as `nova show`.

This will help with troubleshooting, and will enable more informative bug reports.

Copy of whiteboard contents:

This functionality was discussed as part of the ramdisk API, and will be fulfilled by allowing the ramdisk's process to POST log data back to Ironic's API service. Some notes were captured here:

Setting status back to confirmed because the spec is not yet approved, and I do not see any code in-progress.
