#119 implements support for multiple connections in Uncloud config. uc tries each connection in the specified order until one succeeds.

current_context: default
contexts:
  default:
    connections:
      - ssh: ubuntu@1.2.3.4
      - ssh: root@5.6.7.8
      - ssh: user@9.10.11.12

To prioritise a particular connection, a user can edit the config and put the connection on the first place.

An interactive uc command for choosing the first/default connection would be handy. For example, we can extend the uc ctx command. Use up/down arrows to choose the context. Then, before pressing enter, you can press 'c', and a nested selector appears that allows you to select the default connection for that context (which is optional).
