Changelog Description

Render: Add render targets like "Local Render" and "Use Existing Frames".

Additional review information

Fix #375

This has some overlap with ynput/ayon-blender#217 in Blender because I've tried to set up the local render instances in a 'similar' manner using the data from the expectedFiles like the farm jobs would. This way, we can hopefully ensure as much as possible that both flow through the same publishing steps. The end goal would be to unify in such a way that potentially - it could even be shared or inherited from to avoid needing to maintain unique code flows for this between Maya, Blender, etc. and likely we should look into then also matching similar in Fusion, Nuke, Houdini, etc.

Testing notes:

Requires: ynput/ayon-deadline#223

1. The different Render Targets "Local Render", "Use Existing Frames" and "Farm Render" should work:
   • Local Render
   • Use Existing Frames
   • Farm Render
2. Should work correctly with multiple renderlayers (it should render the correct layer for each)

I can set Local Machine Rendering and start rendering but it never stops and starting over and over from the begining of the rendering time range...in my case 1001-1050 I waited 3x times going over and over but then killed the process as it seemed it wont stop anytime.
It might be better to call the local render shorter so it matches the farm rendering setting too as now its a bit long.

here my rendered seq and the already rendered frame which get rendered again (see date/time of creation)

I was rendering to multilayered EXR with GPU render mode of Arnold. so just single image sequence should come out.
