Send to CQ by default and add --no-commit flag + cleanup.

Send the created CL to the CQ right away upon creation.
Add a --no-commit flag that can be specified to avoid that.
Remove the trybot status feature (--status) and the commit CL
feature (--commit).

BUG=chromium:433305
TESTED=Ran:
tools/autoroller/roll_webrtc_in_chromium.py --chromium-checkout /ssd/chrome/src --dry-run --ignore-checks
and verified it didn't trigger tryjobs or sent to CQ. Then I ran:
tools/autoroller/roll_webrtc_in_chromium.py --chromium-checkout /ssd/chrome/src --ignore-checks
and verified it was sent to CQ.
