NC | CLI | InvalidType Error | Replaced hard coded command types list with a dynamic list

[romayalon]

Describe the Problem

While adding a new CLI command, we want to always add the new type to the list mentioned in CLI invalidType error message.

Explain the Changes

1. Replaced the hard coded CLI types list to be dynamic so we won't need to add it to the list manually.
