Replace retryCount with timeout

Move timeout option to common options. Update help file with draft information how to use --timeout option with "emulate android" command. Update common lib where the following change is applied:
When starting Android emulator we were using --retryCount option, which is difficult to be explained. It it replaced with --timeout option, which is the allowed time to start the emulator device(wait to boot). The default value is 120 seconds. retryCount option is removed as it is not used anymore.
