Deadline: provide default user credential fields in studio settings

[kalisp]

Changelog Description

Some studios might have only single user/password credentials for communication with Deadline webservice. This PR provides new fields in Studio Settings which could be used as default values. These could be overridden by values provided by artists in Site Settings if necessary.

Additional info

AYON secrets cannot be used as artist don't have access to those (and this runs in Tray). I am expecting pushback from customer though.

Testing notes:

1. enable on Deadline > Tools > Configure Repository Options > Web Service Settings > Require Authentication
2. set passwor in Deadline > Tools > Manage Users > Webservice password
3. build and install Deadline addon (remove existing unzipped from AppData)
4. provide credentials in ayon+settings://deadline/deadline_urls (could be same as from Deadline: webservice password #200 - just delete them first from Site Settings (on Studio page)
5. publish something to DL, check output from Collect Deadline User Credentials

Artists don't have permissions to read secrets (kinda point of secrets). So they can't access the password value.

Hmm, was worried about that, so reverted to plain string field.
We need password Setting key and probably fix Since settings are sent to clients, secrets provide a way to hide sensitive data from users. in https://ayon.ynput.io/docs/admin_server_provisioning/#secrets as it points that secrets could be used (but actually cannot, just for use in services).

Well artists don't have access to settings tab. But they can read them... If we would add them access to secrets, it would be the same.
