[Feature, UI] allow passing cloud-init user-data on deployment and power-on via UI

[Dmitrii Shcherbakov]

Currently it is only possible to specify cloudinit-userdata via API and not via the UI which hides this functionality from a user. It would be good to have this functionality exposed to provide similar experience to private and public cloud platforms (e.g. OpenStack or AWS allow you to specify userdata before deployment).

Various ways to provide userdata:

1) enlistment time (via preseed files in /etc/maas);
2) deployment time (api call);
https://github.com/maas/maas/blob/2.4.2/src/maasserver/api/machines.py#L509-L515
3) power-on (api call).
https://github.com/maas/maas/blob/2.4.2/src/maasserver/api/nodes.py#L745-L751

maas maas machine deploy <system_id> user_data=<b64-encoded userdata>
maas maas machine power-on <system_id> user_data=<b64-encoded userdata>

We should consider allowing users to upload and store cloud-init user-data in addition to supplying it at deployment time.

[Jochen Wezel (jwezel)]

The process described at https://docs.maas.io/2.5/en/nodes-custom#cloud-init needs a GUI solution.

The UI should provide 2 types of user scripts for deployed machines
1. Script for ALL deployed machines, configurable at e.g. http://maas-server:5240/MAAS/settings/scripts/
   - multiple scripts are required for different platforms, e.g. Windows vs. Linux
   - optional: multiple scripts are required for different operating systems, e.g. CentOS vs. Ubuntu
2. Script for single deployed machines, configurable at e.g. http://maas-server:5240/MAAS/#/machine/8te8qw
