RFC0027 CLI Support for Generic Per-Route Options [main] (#3372)

* Add MinVersionPerRouteOpts check for create and update route commands
* Route command in the v7/commands
* Changed typed route options to an untyped map
* Change DisplayText to DisplayWarning for flag spec err
* Output an error if at least one option is specified incorrectly
* New integration test and adjustments of other tests
* Consistent naming: per-route options vs route specific options
* Rename least-connections to least-connection
