Hello Alexey Serbin, Kudu Jenkins, Grant Henke, Hao Hao,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).
Change subject: hms: allow for tooling to run without Kudu plugin

hms: allow for tooling to run without Kudu plugin
Currently, whenever an HMS client successfully connects to the HMS, it
checks the various HMS service configurations (e.g. that it is using the
Kudu-HMS plugin), returning an error if any are misconfigured. This is
important to make it much more obvious when the Kudu Master's HMS
synchronization is misconfigured.
It is still useful for other HMS clients (e.g. that used by the HMS
tooling) to operate on an HMS instance that is not configured with the
Kudu-HMS plugin et al.
This patch removes the requirement by plumbing the option to the HMS
client as a member of ThriftOptions. This was the most straightforward
way to plumb this option from the HmsCatalog to the HmsClient, given the
templating layered in between them for HA. Besides, we can use this
option in the future if we ever want to verify the configuration of
Thrift-based clients for other services (e.g. Sentry).
This patch additionally allows the -hive_metastore_sasl_enabled flag to
be used without the -keytab flag if not using a kserver. Tool users
should just be able to kinit to authenticate. To get this behavior, I've
gated gflag validator on the stable -fs_wal_dir required flag.
To test, I added an HmsMode that starts the HMS without the Kudu-HMS
plugin installed and used it in a couple of HMS tooling tests. I
considered reusing the ENABLE_HIVE_METASTORE HmsMode, but opted not to
since some tests are greatly simplified by ENABLE_HIVE_METASTORE having
the Kudu-HMS plugin installed (e.g. restarting the HMS isn't required to
enable the Kudu-HMS integration).
