IMPALA-5147: Add the ability to exclude hosts from query execution

This commit introduces a new startup option, termed 'is_executor',
that determines whether an impalad process can execute query fragments.
The 'is_executor' option determines if a specific host will be included
in the scheduler's backend configuration and hence included in
scheduling decisions.

Testing:
- Added a customer cluster test.
- Added a new scheduler test.
