Proposal: add seleniumServerStartTimeout in Local DriverProvider

[akirakoyasu]

It's nice to specify how long time the Local DriverProvider waits for the selenium-webdriver server to start.

The Local DriverProvider starts local selenium-webdriver server, and waits for the server in 30,000ms now. That's because DriverService#start() of selenium-webdriver/remote has an arg opt_timeoutMs default 30,000ms.

30,000ms is almost enough long, but that depends on environment.

Add a note that it's only for local selenium servers

@sjelin
Thanks, I fixed it. But...
Or other expression is better?

In your last comment you asked: "Or other expression is better?"

What does that mean?

[sjelin]

nit: should be "waiting for a local Selenium Standalone Server

[akirakoyasu]
