[NEW] Allow to set default department and location sharing on SMS / WhatsApp integration

[renatobecker]

This PR adds a new setting that allows defining a default Omnichannel department for SMS/WhatsApp integration.
So, if the setting is defined, all new incoming chats received through the SMS integration will be routed to the configured department.

In addition(CLOSES RocketChat/feature-requests#304), a new whatsApp feature will be supported: Inbound/Outbound location sharing.
Both agents and WhatsApp users will be able to share their locations, as displayed below:

Also, part of the code has been rewritten to make it simpler and more readable.

Dear @renatobecker ,

I think this pull request may be broking the other sms integration, since it's forcing the integration to declare an "extra" object inside returnData in the "parse" function. I'm currently developing a new integration for other sms/whatsapp service provider and it only works if latitude and longitude are declared.

I think it may be broking the other integrations (but I'm not sure) such as mobex and voxtelesys
