[dev-rafael-arevalo]

Define confirm and cancel reservations with followings considerations:

• Put a map service (Google, Leaflet, etc) with the address of host.
• Define nights reservations period in days
• Update With Cancel and Confirm states

Validations (If the start date has passed, not possible to cancel, if the end date has passed away, not possible to cancel and confirm).
