The core change here is to the loop in
`SimpleRegionNormalizer#computeMergeNormalizationPlans`. It's a nested
loop that walks the table's region chain once, looking for contiguous
sequences of regions that meet the criteria for merge. The outer loop
tracks the starting point of the next sequence, the inner loop looks
for the end of that sequence. A single sequence becomes an instance of
`MergeNormalizationPlan`.

Implement a rate limiter for the normalizer. Implemented in terms of
MB/sec of affacted region size (the same metrics used to make
normalization decisions). Uses Guava `RateLimiter` to perform the
resource accounting. `RateLimiter` works by blocking (uninterruptible
😖) the calling thread. Thus, the whole construction of the normalizer
subsystem needed refactoring. See the provided `package-info.java` for
an overview of this new structure.
Introduces a new configuration,
`hbase.normalizer.throughput.max_bytes_per_sec`, for specifying a
limit on the throughput of actions executed by the normalizer. Note
that while this configuration value is in bytes, the minimum honored
valued `1_000_000`. Supports values configured using the
human-readable suffixes honored by `Configuration.getLongBytes`

Change the test to wait for evidence that the active master has seen
that the backup master killed by the test has gone away. This is done
before proceeding to validate that the dead backup is correctly
omitted from the ClusterStatus report.
Also, minor fixup to several assertions, using `assertEquals` instead
of `assertTrue(...equals(...))` and correcting expected vs. actual

This patch adds the ability to discover newly added masters
dynamically on the master registry side. The trigger for the
re-fetch is either periodic (5 mins) or any registry RPC failure.
Master server information is cached in masters to avoid repeated
ZK lookups.
Updates the client side connection metrics to maintain a counter
per RPC type so that clients have visibility into counts grouped
by RPC method name.
I didn't add the method to ZK registry interface since there
is a design discussion going on in splittable meta doc. We can
add it later if needed.
