IMPALA-7450. Set thread name during refresh/load operations

This adds a small utility class for annotating the current thread's name
during potentially long-running operations such as refresh/load. With
this change, jstack output now includes useful thread names like:

During startup:
  "main [invalidating metadata - 128/428 dbs complete]"

While loading a fresh table:
  "pool-4-thread-12 [Loading metadata for: foo_db.foo_table] [Loading
   metadata for all partition(s) of foo_db.foo_table]"

Pool refreshing metadata for a particular path:
  "pool-23-thread-5 [Refreshing file metadata for path:
   hdfs://nameservice1/path/to/partdir..."

This patch is tricky to automate tests for, but I verified it manually
by jstacking a catalogd while performing some workload. Also added a
simple unit test to verify the thread renaming behavior.
