HBASE-24802 make a drop-in compatible impl of htrace APIs that does not do anything

[busbey]

first pass. works for mvn test against the shaded testing utility in HBase 2.2.5. need some more hbase/hadoop version combos.

[busbey]

force push was to rebase onto current master branch

[busbey]

Looks like the new test works now to match the testing results I get locally.

ATM this test will only set build status (the little ✔️ or ❌ on a commit and the "checks have passed/failed" at the bottom of the PR discussion) and does not do a comment. If anyone has an issue with this please let me know and I'll see what our options are.

the test included here checks the no-op replacement for use with HBase 2.2 and 2.3 combined with Hadoop 3.2 and 2.10.

[Apache9]

So we will depend on this jar in hbase and exclude all other htrace dependencies?

[busbey]

Yep! And an existing install can delete the normal htrace jar and put this one in place.
