Recommend allowing the license server be configurable.

The license_server I am using consists of the following format…

www.example.com
&token={{token}}
&account={{account}}
&_releasePid={{releasePid}}
&_widevineChallenge={{widevineChallenge}}

I am able to construct everything beyond the widevineChallenge before instantiating shaka.player.DrmSchemeInfo.

I need to be able to append the widevineChallenge to the license server before the request gets sent by shaka.util.LicenseRequest.send().

var license_server = ...

return new shaka.player.DrmSchemeInfo(
    'com.widevine.alpha',
    license_server,
    false, /* withCredentials */
    null, /* licensePostProcessor */
    licensePreProcessor /* licensePreProcessor */
);

function licensePreProcessor(license_request_info) {
    // modify license server somehow
}

Currently the license_request_info has body and headers (https://github.com/google/shaka-player/blob/master/lib/player/drm_scheme_info.js#L142).

• Possibly add a way to pass query string parameters?
• Possible add a way to manipulate the license server beyond string manipulation?

We can add a licenseServerUrl override to the licenseRequestInfo object.
