Add record option to storkctl migrate command

[phenixblue]

FEATURE REQUEST:

It would be nice to have storkctl record the specific command used to create the migration object as an annotation on the migration object. This would be similar to the --record option for many kubectl commands.

Not sure if it would be best to have this done by default, or on-demand using an argument passed (ie. --record).

This would be helpful for troubleshooting migration operations to have a providence of sorts for what was run.
