VIP: Run Name not handled

[wxtim]

Describe the bug

If you use the --run-name option with cylc install you have to specify the run name in the ID with cylc play, unlike the numbered runs where cylc assumes you mean the most recent install:

cd ~/cylc-src/foo
cylc vip --run-name bar
...
# validate and install OK
...
WorkflowFilesError: No flow.cylc or suite.rc in /home/h02/tpilling/cylc-run/foo  # It's in foo/bar

Expected behavior

Either

1. Throw --run-name out from Cylc VIP as an invalid option.
2. Allow --run-name and modify the workflow id given to Cylc play accordingly.
3. Modify cylc install and cylc play so that cylc install can mark the last install. cylc play uses marker to infer run-name to use.

Additional context

It might be worth checking various permutations of run-name & no-run-name looking for other bugs like this one.

I think number 2 is the correct answer - number 3 is fairly invasive of existing functionality and risks creating other issues. Number one is unnecessarily unhelpful.
