feat: implement resources and rooms overview

[st3iny]

Fix #3185

Requires nextcloud/cdav-library#890

Please checkout the above branch, build it and npm link it (@nextcloud/cdav-library).

TODO

• Implement a list (modal?) that shows all available rooms
• Add an action to show the free busy slots for a room (action/button?)

How to use

1. Install https://github.com/nextcloud/calendar_resource_management
2. Run the following script to add some rooms:

occ calendar-resource:building:create 'Arkham Asylum' \
    --address 'Amadeus Way, Gotham NG11 0AS' \
    --description 'Elizabeth Arkham Asylum for the Criminally Insane' \
    --wheelchair-accessible false
occ calendar-resource:story:create 1 '1st floor'
occ calendar-resource:story:create 1 '2nd floor'
occ calendar-resource:room:create 1 arkham_meeting_1 'The Joker' joker@arkham-asylum.com 'meeting-room' \
    --contact-person-user-id amadeus \
    --capacity 10 \
    --room-number 404 \
    --has-phone '+1 555 777 123' \
    --has-video-conferencing true \
    --has-tv false \
    --has-projector false \
    --has-whiteboard false \
    --wheelchair-accessible false
occ calendar-resource:room:create 2 arkham_meeting_2 'Bane' bane@arkham-asylum.com 'other'

3. Run the cron job multiple times to update metadata: php -f [path_to_nextcloud]/cron.php

The data will be fetched automatically and is available via:

this.$store.getters.getRoomPrincipals // get an array room objects
this.$store.getters.getResourcePrincipals // get an array resources objects

Exemplary data

const someRoom = this.$store.getters.getRoomPrincipals[0]
someRoom.dav.roomAddress
someRoom.dav.roomBuildingAddress
someRoom.dav.roomBuildingRoomNumber
someRoom.dav.roomBuildingStory
someRoom.dav.roomFeatures
someRoom.dav.roomId
someRoom.dav.roomSeatingCapacity
someRoom.dav.roomType
// [...] etc.
