CASSANDRA-15677 Add shutdown to JMX thread pool to avoid metaspace errors associated with thread leaks. There are still other thread shutdown issues remaining, but this seems to be the most serious one.

Switches ValidationExecutor's work queue to LinkedBlockingQueue to
avoid blocking AntiEntropyStage when the executor is saturated. This
requires VE.corePoolSize to be set to concurrent_validations as now
it will always prefer to queue requests rather than start new threads.

This commit also adds a hard limit on concurrent_validations, as allowing
an unbounded number of validations to run concurrently is never safe.
This was always true, but setting a high value here is now more
dangerous as it controls the number of core, not max, threads.
This hard limit is linked to concurrent_compactors, so operators may
set concurrent_validations between 1 and concurrent_compactors.
The meaning of setting it < 1 has changed from "unbounded" to
"whatever concurrent_compactors is set to".

This safety valve can be overridden with a system property at startup
and/or a JMX property.

CASSANDRA-9292 removed the 1hr timeout on prepare messages, but this
was inadvertently undone when CASSANDRA-13397 was committed. As nothing
long running is done in the repair phase anymore, this timeout can
safely be reduced.

If using RepairCommandPoolFullStrategy.queue, the core pool size
for repairCommandExecutor must be increased from the default
value of 1 or else all concurrent tasks will be queued and no
more threads created.

The tests were constantly failing for the cdc test run due to the fact
that CDCSizeTracker.shutdown was throwing a NPE if the method was called
while CDCSizeTracker was not started.
The fix ensure that the test start the commitlog and that
CDCSizeTracker.shutdown is a NOOP if the tracker has not been started.

CASSANDRA-11050 introduced dropped columns but excluded it from schema digest computations, with
a comment to include the table in the next major release - 4.0.

The patch now includes DROPPED_COLUMNS in the schema digest computation.
