krane restart

[dturn]

Problem

Add the krane restart command, https://docs.google.com/document/d/1oInUsKplYGNWTymPY48xtDCx3x4Cwc-phcEKUkt2v4U/view# has details on flags that need to be supported.

This is blocked by #524.

The actual restart task doesn't match our standard interface convention. Please change perform/perform! to run/run! as well as ensure that new & run use the same conventions as the other tasks, its fine to do this in a separate PR.

Possible solution

Build a thor task that calls RestartTask.new.

Alternative solutions

Depending on the difficulty of supporting --verify-result=false this may need to be split into a second PR. We've discussed adding a new command that can stand alone verify a namespace, if a second PR is required please do it with an eye towards supporting such a command.

Acceptance criteria

• The command must work with all flags
• The command should have tests.

Additional context

#256 is the tracking issue for the new CLI.

#548

[dturn]

The initial pass was added in 548. We still need to support the -f` flag. Thor merged rails/thor#674 (allow repeatable options), but they haven't cut a release, depending on the timeline we may point at a sha.

To help us prioritize work I've cut separate issue for adding the -f flag. #558
