Some small fixes found while doing an e2e test with devserver changes.

1) Alex's change to not exit 0 totally now clobbers you shadow config
even if you say no.
2) Release config should be updated for R27.
3) Site RPC interface -- better logging.
4) Site_Suite didn't actually allow an int override -- kept on casting it
to a string.

BUG=None
TEST=Ran through devserver test using cli/atest suite create and setup
autotest with shadow config.
