IMPALA-6508: add krpc test flag

This change adds a flag "--use_krpc" to start-impala-cluster.py. The
flag is currently passed as an argument to the impalad daemon. In the
future it will also enable krpc for the catalogd and statestored
daemons.

This change also adds a flag "--test_krpc" to pytest. When running tests
using "impala-py.test --test_krpc", the test cluster will be started
by passing "--use_krpc" to start-impala-cluster.py (see above).

This change also adds a SkipIf to skip tests based on whether the
cluster was started with krpc support or not.

- SkipIf.not_krpc can be used to mark a test that depends on krpc.
- SkipIf.not_thrift can be used to mark a test that depends on Thrift
  RPC.

This change adds a meta test to make sure that the new SkipIf decorators
work correctly. The test should be removed as soon as real tests have
been added with the new decorators.
