Remove features that relied on printed exception parsing

[alexander-yakushev]

This PR removes features that depended on the now removed analyze-stacktrace op which used Haystack parsing functionality:

• Manual cider-stacktrace-analyze-string and cider-stacktrace-analyze-at-point functions.
• Automatic stacktrace parsing in log viewer.

To replace this functionality, the latest cider-nrepl now provides much better ability to jump to functions and methods printed in the stacktrace (see clojure-emacs/orchard#320). I went through examples/tests in Haystack repository, and the improved Orchard can jump to most of them directly from any buffer, including REPL, e.g.:

clojure.lang.AFn.applyToHelper clojure.lang.Compiler$InvokeExpr.eval nrepl.middleware.interruptible-eval/evaluator/fn/fn clojure.main/repl/read-eval-print/fn clojure.core$eval.invokeStatic clojure.core$with_bindings_STAR_.doInvoke clojure.main$repl$read_eval_print__9110$fn__9113.invoke

• You've updated the changelog (if adding/changing user-visible functionality)
• You've updated the user manual (if adding/changing user-visible functionality)

I think it's good to replace these obsolete commands with some message explaining why there were removed. I don't think they had many users, being relatively new, but adding a message like "Use x instead" is never a bad idea IMO.

Good point! Will do.

Looks good to me, sans my small remark that it might be a good idea to convert the remove interactive commands to just a message saying that users are supposed to use something else instead. (before we fully remove them a few releases down the road) You can also gut them and use make-obsolete https://www.gnu.org/software/emacs/manual/html_node/elisp/Obsolete-Functions.html
