Allow custom ubuntu timeouts

Default timeouts of 900 and 1500 seconds which are suitable for
upstream CI are too long for downstream CI causing redundant
15 minutes retries while 2-3 minutes are enough to make a decision
that something went wrong. This patch allows
configuring custom values for ubuntu vm connectivity timeouts.
