Johannes Batzill 1115a5083b Add Paths support and error improvements (#11)
This change is adding the concept of Paths.
A repository and space always have a Primary Path which always is represents the ancestry to the root space.
All access history / resource visibility / child listings / UI traversal / etc. is done via that path.

Additionally, repos and spaces can have Alias Paths, which as the name states are aliases. via the primary path.
They sole impact is that a space or repo can be reached via different paths from the UI / rest apis / git apis.
This fulfills two major purposes:
- Customers can rename or move projects and spaces without breaking any existing references from CI pipeliens / code bases / local repos / ...
- Customer can create shorter aliases for important repos when in harness embeded mode! (acc/org/proj/repo can be shortened to acc/repo, or acc/repo'

Apart from the path changes, this PR adds:

Improved User facing errors
Improved internal error handling and wrapping
update / rename operation for repo and space
path list / delete / create operation for repo and space
