v0.7.5

[0.7.5] - 2021-10-19

Added

• cb uri displays the URI for a cluster with the password displayed as
  black-on-black so you can still copy and paste it, but it has less of a
  chance of being unexpectedly leaked
• cb info now shows source cluster id for replica clusters.

Fixed

• Replica clusters show up in cb list as well as tab completion for clusters.
