IMPALA-10535: Add interface to ImpalaServer for execution of externally compiled statements

The ExecutePlannedStatement interface allows an externally supplied
TExecRequest to be executed by impalad. The TExecRequest must be fully
populated and will be sent directly to the backend for execution.

The following fields in the TExecRequest are updated by the coordinator:
- Hostname
- KRPC address
- Local Timezone

In order to add the interface to ImpalaInternalService.thrift, several of
the thrift classes were moved to Query.thrift to avoid a circular
dependency with Frontend.thrift.

Added functionality to format and dump TExecRequest structures to path
specified in debug flag dump_exec_request_path.

A start timestamp field has been added to TExecRequest to represent the
interval in the query profile between when the request was sent by the
external frontend and handled by the backend.

A local timestamp field has been added to the Ping result struct to
return the current backend timestamp. This is used by the external to
frontend to populate the start timestamp.

Also included is a change to avoid generating silent AnalysisExceptions
during table resolution.

Tested with TExecRequest structures populated by external frontend.
Local timezone change tested withe INT64 TIMESTAMP datatype
