Maya: Build workfile by template

[iLLiCiTiT]

Modified source PR. Code was moved from openpype/lib into openpype/pipeline/workfile to match refactor goals we're working on right now.

Was modified by PR which changed how placeholders work primarily because of mongo queries.

Brief description

Following discussion #2013 and resumption of work from ellipsanime #2202

Templated Build Workfile

Building a workfile using a template designed by users. Helping to assert homogeneous subsets hierarchy and imports. Template stored as file easy to define, change and customize for production needs.

1. Make a template

Make your template. Add families and everything needed for your tasks. Here is an example template for the modeling task using a placeholder to import a gauge.

If needed, you can add placeholders when the template needs to load some assets. OpenPype > Template Builder > Create Placeholder

• Configure placeholders

Fill in the necessary fields (the optional fields are regex filters)

- Builder type: Wether the the placeholder should load current asset representations or linked assets representations

- Representation: Representation that will be loaded (ex: ma, abc, png, etc...)

- Family: Family of the representation to load (main, look, image, etc ...)

- Loader: Placeholder loader name that will be used to load corresponding representations

- Order: Priority for current placeholder loader (priority is lowest first, highet last)

• Save your template

2. Configure Template

• Go to Studio settings > Project > Your DCC > Templated Build Settings
• Add a profile for your task and enter path to your template

3. Build your workfile

• Open maya

• Build your workfile

Testing notes:

• Deadline should find representation resources as did (do we need that functionality?)
• Placeholder templates should work as described above
