Support more "digger plan" options

[fleroux514]

A few ideas that would be very helpful:

digger plan -p * To force running a plan on all projects digger plan --skip-cmds checkov* The ability to specify a regex for the commands we wish to skip (checkov in this case). digger plan --no-locks Run all plans without acquiring the locks, just to see if it works (the plan output comment should add a warning that this option that used)

And being able to combine all of those options: digger plan -p * --skip-cmds checkov* --no-locks
