Add the ability to set watch timeouts.

[barney-s]

Allow setting shorter watch timeout for the first time alone.

What this PR does / why we need it: We have seen in some evnironments (where requests are tunnelled) setting up the (first) watch is blocking if there are no resources available to watch. This causes the apply loop to be blocked when setting up watches before apply.

The test that is failing here is passing when i run it locally. Not sure what is happening here. !! @justinsb
