conserver: T4717: Support for setting a name for console-server devices

This adds a new 'alias' property to the console-server device definition
to allow users to connect to a console using a human-readable name
rather than just the device name.

For a configuration like:
service {
  console-server {
    device ttyUSB0 {
      speed 115200
      alias my-server
    }
  }
}

Users can connect either by doing `connect console ttyUSB0`, or
`connect console my-server`.

Names:
* Must be unique
* Are limited to 128 characters
* Are optional - if not specified, only the `connect console ttyX`
  form can be used
