Automated tests for quota checks

[PVince81]

Matrix dimensions:

• dimension 1:
  • "enough quota"
  • "not enough quota"
• dimension 2:
  • "old dav endpoint"
  • "new dav endpoint"
• dimension 3: upload type:
  • "regular upload"
  • "chunked upload" (if old dav, use "OC-Chunked" approach, if new dav, use the "uploads" endpoint)
  • "OC-Chunked code" for new dav endpoint
• dimension 4: upload target:
  • "regular folder"
  • "received shared folder"
  • "overwrite file inside received shared folder"
  • "overwrite received shared file (direct file share, in this case the quota check must happen on the file's storage, special case!)
• dimension 5: whether new file or overwriting

I thought of these cases while looking into a potential fix for owncloud/core#28159 which will likely affect all of the cases above...

[PVince81]

some ideas to make implementation for this easier:

• have a scenario step "for all upload types" that does 3 uploads of the same file using the 3 ways

[PVince81]

Let's add a new upload step: `When User "$user" uploads file "$file" to "$target" with any dav and any upload type".

This would then run the matrix between "new dav, old dav" and "non-chunked and chunked" dimensions.

Everything else to be implemented in separate scenarios.

Tests hypercube implemented here: owncloud/core#28160.

[PVince81]

added new dimension "new file vs overwriting" which also triggers different code paths.
