IMPALA-7531: Daemon level catalog cache metrics

This patch adds the aggregated CatalogdMetaProvider cache stats to
the catalog metrics on the coordinators. They can be accessed under
<coordinator>:<web-port>/metrics#catalog.

These metrics are refreshed at the end of planning, for each query run.

Testing:
-------

Visual inspection by running a few queries locally and making sure
stats are updated. Also modified existing tests to account for this
behavior.
