OpenRV: added integration

[kalisp]

Changelog Description

This PR is adding OpenRV - open source version of RV - image and sequence viewer for VFX and animation artists - to the list of applications.

This allows to set path to OpenpRV binaries in Applications addon and add it to Anatomy > Attributes for particular project to show up in Ayon Launcher.

Additional info

Code for addon itself is https://github.com/ynput/ayon-openrv . Doesn't contain OpenRV binaries because of licensing!

Currently implemented and working workfile workflow. There was annotation auto creator but workflow was unfinished. Unsure how the workflow should look like and what should have produced to be able to finish it. Open for comments.

Documentation for this PR here ynput/ayon-documentation#130

Testing notes:

1. build new Applications addon via server_addon/create_ayon_addons.py
2. deploy it to Ayon server and restart
3. use new Applications addon in bundle
4. set path to OpenRV in ayon+settings://applications/applications/openrv/variants/0

5. set `OpenRV` to `ayon+anatomy://ayon_test/attributes`

I'd say there's no point merging this now with the existence of ayon-openrv

You mean ayon-core, it is still required to have it there even if the code itself is in separate repo. We still need to expose OpenRV in a list of applications.
