Add submit records to query output.

Add a command line option to the gerrit query ssh command to include
submit records in output.

This facilitates the querying of information relating to the submit status
from the command line and by API clients, including information such as
whether the change can be submitted as-is, and whether the submission
criteria for each review label has been met.  Example output:

  submitRecords:
    status: NOT_READY
    labels:
      label: Verified
      status: OK
      by:
        name: James E. Blair
        email: corvus@example.com
        username: corvus
    labels:
      label: Code-Review
      status: NEED
