[16.0][IMP] resource_booking: get_intervals

[norlinhenrik]

Current workflow: Create a booking with a booking type, then check availablility.

Needed workflow: Check availability for a booking type without creating a booking.

_get_intervals() has a new input argument:

• start_dt
• end_dt
• combination=None
• type=None

Hi @pedrobaeza, @ows-cloud,
some modules you are maintaining are being modified, check this out!

Don't use type, as it's a semi-reserved word. Use for example rb_type. Anyway, I don't get the sense of the code, as you are still assigning a booking type.
