* Allows creating new remote clusters without providing a password
If the endpoint receives a request with no password, it will generate
one internally and return it in the response, so the frotend can show
it to the user.
* Use a random string instead of a UUID for the generated password
* Update function name to avoid CString reference and adds assertion
* Update server/channels/utils/textgeneration.go
