POC: Expand Patch Operations

[Qualizorg]

Related to #442, #307, #297

Implementation to support replace, set, add, remove, increment patch operations, excluding move.

Both implementations follow expression + path, inspired by #307 .

Expression approach can't work with ArrayIndexExpression (x => x.Address.Tags[0]), can make it work if it brings value, nevertheless same goal can be achieved over string path approach (/address/tags/0)

Questions

1. InMemoryRepository needs rework to handle the other operation types, how critical is it?
2. Decide if bulk patch operations per partition key are valuable.

Need feedback regarding approach and any major optimizations we can perform. @IEvangelist @mumby0168

Tasks

• [x] Rework Replace Operation + Unit Tests
• [x] Implemented Set Operation + Unit Tests
• [x] Implemented Add Operation + Unit Tests
• [x] Implemented Remove Operation + Unit Tests
• [x] Implemented Increment Operation + Unit Tests
• [ ] Document methods with Microsoft Docs
• [ ] Add all corresponding tests to DefaultRepositoryTests
• [ ] Remove commented code (dependant on question 1)

[Qualizorg]

Updated DefaultRepository.Update.cs to return etag as value.

Add Operation doesn't work properly with lambda.

Cosmos exception Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'QV.OrganisationsComponent.Domain.Department' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\r\nPath 'departments[2]', line 1, position 703.

This is due the fact that x => x.Departments is a list and TValue from .Add expects it to be a list.

Needs more work.
