Add to API::Google universal query() method

[pavelsr]

Make the library without limitations.

In particular, in current implementation there is no way to pass to Events.list() timeMax and timeMin params that is inconvenient.

More universal method would be:

$gcal_api->query({
  resource => 'Events'
  method => 'delete'
})

Also it will be great if object oriented way would be implemented (see method chaining)

$gcal_api->Events->delete($event_id)

As examples of good API implementation see source code of MojoX::CloudFlare::Simple, WWW::Telegram::BotAPI and Mojo::Cloudflare
