fix(gce-spot-termination): prolong wait time on logs fetch error

In case of error during getting logs from gce logging api, next logs
fetch is done immediately. In case of too many queries/min error, this
will fail even more.

This commit fixes this behavior by not making immediate logs fetch
again. Also if there was a failure, make next query to ask for logs from
failed period too.
