chromite: Address some line-too-long lint errors.

Mostly these are pydoc firstline summaries.

This batch addresses those summaries that are >83 characters,
and can't be fixed by moving the terminating """ to a new line.

After this, pydoc summaries of single-line comments that are
<=83 characters are the only remaining things over 80 chars in
chromite.

BUG=b:233893248
TEST=cros lint + CQ
