General: Move load related functions into pipeline

[iLLiCiTiT]

Brief description

Loading workflow specific functions were moved to openpype.pipeline.load and their related to other places.

Description

Implemented functions to filter containers into few categories to be able get outdated containers or check for them easier. Added helper client function to find out if version id is latest version.

Functions marked as deprecated in openpype.lib are get_latest_version, is_latest and any_outdated.

Testing notes:

Submission to deadline should properly detect last version.
Check for outdated containers should work in hosts

• Aftereffects
• Harmony - loading should also mark outdated containers with red and latest with green color
• Houdini
• Maya
• Photoshop
