Custom RBE timeout for non-test actions

[rjobredeaux3]

Description of the feature request:

RBE action timeouts for test actions can be increased using the --test_timeout flag, otherwise the default timeout for RBE actions is one hour.

Bazel can already request a different timeout from RBE (read from execution info here, into SpawExecutionContext here, and into the remote action builder here), but there is no API to do so for non-test actions. My dirty fix at the moment is this + setting a timeout in the execution_requirements of the ctx.actions.run call. It works, though I suspect it would break anyone using "timeout" as a tag in their rule (this could be worked around by maintaining 2 separate lists for tags specified in target definitions vs execution_requirements specified from a ctx.actions.run call).

More generally it seems the list of exec_info keys that we let users specify is intentionally short, so filing this as a feature request in case my approach has unintended consequences I haven't thought of.
