Original issue's description:
> SSL and add handlers in EmbeddedTestServer
>
> As part of the migration of tests to EmbeddedTestServer, this CL modifies
> EmbeddedTestServer to support SSLServerSocket and to add shared default handlers
> that can be used by tests to mirror the SpawnedTestServer handlers. The major
> changes are:
>
> - SSL support through SSLServerSocket
> - Adding SSLServerConfig to configure SSLServerSockets.
> - Setting up default handlers for BrowserTestBase tests.
> - Asynchronous HttpResponse.
> - Moving EmbeddedTestServer to the net:: namespace.
