Move generic code to HttpOrSpdyChooser to simplify implementations

Motivation:

HttpOrSpdyChooser can be simplified so the user not need to implement getProtocol(...) method.

Modification:

Add implementation for the method. The user can override it if necessary.

Result:

Easier usage of HttpOrSpdyChooser.
