IMPALA-5259: Add REFRESH FUNCTIONS <db> statement

Before this patch, Impala relied on INVALIDATE METADATA to load
externally added UDFs from HMS. The problem with this approach is that
INVALIDATE METADATA affects all databases and tables in the entire
cluster.

In this patch, we add a REFRESH FUNCTIONS <db> statement that reloads
the functions of a database from HMS. We return a list of updated and
removed db functions to the issuing Impalad in order to update its
local catalog cache.

Testing:
- Ran a private build which passed.
