[pbs-devel] [PATCH backup v3 1/7] pbs-client: use a const for the PBS_REPOSITORY env variable

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

Signed-off-by: Maximiliano Sandoval <m.sandoval@proxmox.com>

Differences from v2:
- Renamed 'System Credentials' section to 'System and Service Credentials':
  System credentials are a special kind of credential, a new paragraph was added
  to explain how to use system credentials.
- Improve documentation wording.

Differences from v1:
- Use the helper on get_encryption_password
- Send "add helper" commit to the past
