Change representation of debug-commands to a set of command names

[yuhan0]

Note: This is a breaking change that sends debug commands to the client as an unsorted
list of command names without key mapping information, as a means of separating
concerns.

Quick draft of the changes suggested in clojure-emacs/cider#2731
If everything looks alright I'll go ahead with adding changelog notes and tests

Before submitting a PR make sure the following things have been done:

• The commits are consistent with our contribution guidelines
• You've added tests to cover your change(s)
• All tests are passing
• The new code is not generating reflection warnings
• You've updated the README (if adding/changing middleware)

We should use a proper name here - the current one was just to convey the relationship with C.

[yuhan0]

:continue-all and :inspect-prompt? Or maybe :inspect-current for p
Would that also call for a command name -> display name mapping on the client side? Right now it's just using the plain command names as overlay titles.

[bbatsov]

You read my mind. I was just writing about some display name mapping on the other ticket. :-)

:continue-all

👍

For inspect - let's have the default command inspect the current value and the other to be inspect-prompt.

[bbatsov]

Same here.

Btw, I guess the second inspect should go in a different PR, as we don't really have that command available currently.

[yuhan0]

Ok, I rebased the conflicts, removed the references to :insPect and renamed :Continue to :continue-all.

Somehow I can't seem to get the test suite working locally - make test reports an unrelated error in the info-test and passes the cider.nrepl.debug tests.

@yuhan0 I see the debug integration test is failing currently on the CI. Seems like a real failure to me.

[yuhan0]

Ok it was a fairly simple change, now all existing tests are passing :)

[bbatsov]

@yuhan0 Just squash the last two commits and we're good to go.

[bbatsov]

Great work! Thanks for tackling this! 🙇
