Tim Armstrong resolved IMPALA-3271.
-----------------------------------
       Resolution: Fixed
    Fix Version/s: Impala 3.0


IMPALA-3271: organise and warn on removed startup flags

Gather all the removed flags in a single place and establish consistent
behaviour.

If the flag is set, a warning is logged. GFlags are initialised before
logging, so the warning goes to stderr instead of the WARNING log.

The affected flags are:
be_service_threads, cgroup_hierarchy_path, enable_accept_queue_server,
enable_partitioned_aggregation, enable_partitioned_hash_join,
enable_phj_probe_side_filtering, enable_rm, llama_addresses,
llama_callback_port, llama_host, llama_max_request_attempts,
llama_port, llama_registration_timeout_secs,
llama_registration_wait_secs, local_nodemanager_url,
resource_broker_cnxn_attempts, resource_broker_cnxn_retry_interval_ms,
resource_broker_recv_timeout, resource_broker_send_timeout,
rm_always_use_defaults, rm_default_cpu_vcores, rm_default_memory,
rpc_cnxn_attempts, rpc_cnxn_retry_interval_ms, staging_cgroup,
suppress_unknown_disk_id_warnings, use_statestore,

Testing:
Ran "start-impala-cluster.py --impalad_args=--enable_rm=true"
and verified that the warning appeared in
logs/cluster/impalad-error.log

Cherry-picks: not for 2.x

> Llama has been unsupported as of Impala 2.3 (CDH 5.5), but it is still possible to start Impala with Llama integration enabled. For Impala 3.0 we can remove this support from the product. This will involve removing user-facing configurations (and related plumbing) that enables Llama to be used as it was before Impala 2.3.
