General: Mongo core connection moved to client

[iLLiCiTiT]

Brief description

Moved core of Mongo connection OpenPypeMongoConnection from openpype.lib into openpype.client. This change makes openpype.client independent from openpype lib functions and can be considered as self contained.

Description

Changed parts of code using OpenPypeMongoConnection to use new source and marked lib functions as deprecated. That is unfortunatelly not possible for classes located there too.

Testing notes:

• Logging to mongo should work (can be validated using LogViewer in tray)
• Webpublisher should work
• Maya shader publishing can be possible (not sure if is used?)
• OpenPype MongoURL can be changed in local settings UI
• Remote (automated) publishing can get and update jobs to do
• Ftrack event server (service) can process ftrack events
• Integration to slack should work
• Project Settings can be loaded and saved
