--bes_timeout=<An immutable length of time.>
Specifies how long bazel should wait for the BES/BEP upload to complete after the build and tests have finished. A valid timeout is a natural number followed by a unit: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). The default value is '0' which means that there is no timeout.
