Azure and Azure-compatible object stores can now be used for repository storage.
Currently only shared key authentication is supported but SAS will be added soon.
The primary source for project info is now src/version.h.
The pgBackRestDoc::ProjectInfo module loads the project info from src/version.h at runtime so there is no need to update it.
This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.
More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.
