Add -create-plan flag to 'src action exec'
Created by: mrnugget
When the -create-plan flag is given the src action exec
command will
create a campaign plan from the produced patches, making it not
necessary to pipe the output to src campaign plan create-from-patches
.
If the execution of the action failed in a subset of the repositories, the user is prompted and asked whether they would create a campaign plan from the successfully produced patches or not.
