Optimize Android device provisioning; refactor to optimize constructor/method args

In this release, I added functionality to migrate Android device provisioning from per-session initialization to pre-suite provisioning.
As part of this optimization, I added persistence of the browser name associated with each GridServer object, as well as the collection of supported "personality" records. In the process, I noticed redundancy in constructor and method arguments. For example, I was specifying both the associated hub URL and the hub port (which is encapsulated in the URL).

NOTE: This is a major-version release because revisions include breaking changes to public interfaces.
