Items (1) & (3) are under review at https://codereview.chromium.org/2016883003/

CL for Item (2) is at https://codereview.chromium.org/2006143011 , but it was decided to delay this until M-54, so I'm just sitting on it until then.

It was decided that hard-coded files in Item (4) can be left where they are, and no action is needed here.

Remove Quirks flag, limit server retries

BUG= 598841 
TEST=Check that disable-quirks-client is no longer on the experimental
flags list.

This removes the disable-quirks-client command line flag, and places a
limit of 10 on the number of times (with exponential backoff) that
Chrome OS will attempt to contact the Quirks server in one session.

Remove first check random delay on older devices

BUG= 598841 
TEST=Not easily testable, as this CL removes code that is no longer
active after a first Quirks server check; we expect nearly all devices
should have made a server check as of M-54, if they're ever going to.
