IMPALA-8583: Add metrics for Basic auth

The patch adds two metrics:
impala.thrift-server.hiveserver2-http-frontend.total-basic-auth-success
impala.thrift-server.hiveserver2-http-frontend.total-basic-auth-failure
which track the number of successful and failed attempts at using
Basic auth to authentication to the hiveserver2 http server.

A followup patch will add similar metrics for SASL attempts on the
beeswax and hiveserver2 binary servers.

Testing:
- Modified existing HTTP auth test to check that the produced metrics
  are correct.
