With change Iff5e96bd80b8f165ccc7d6be09b53208613571eb, we do not need
to pass DEVSTACK_GATE_TIMEOUT anymore to devstack-gate, instead the
value from the build-timeout wrapper is passed.
Remove DEVSTACK_GATE_TIMEOUT for jenkins/jobs/d*.yaml
Increase timeout for all non-grenade jobs by 5 mins since
Iea866e4cc40e149e598f35e010ec855937bdf9ae will use a 10 minute
buffer and the internal timeout should stay the same. The grenade
jobs already have 10 mins of buffer, so no need
adjust the timeout.
Note that the builder devstack-virtual-ironic uses devstack-timeout
for setting DEVSTACK_GATE_TIMEOUT, remove devstack-timeout as well,
it is not needed anymore.
