Allow Sandbox Name to be Passed via Command Line Argument While Using Sandbox Definition File for Other Attributes

[mcarvin8]

Currently, to declare the Sandbox Name to create, you have to either pass it in with the --name argument or list the Sandbox name in a Sandbox Definition File. It has to be 1 approach or the other, or else it will exit with an error.

sf org create sandbox --name Carvin -f config/dev-sandbox-def.json --alias MyDevSandbox --target-org PROD  --set-default
Error (2): The following errors occurred:
  --definition-file=config/dev-sandbox-def.json cannot also be provided when using --name
  --name=Carvin cannot also be provided when using --definition-file
See more help with --help

It would be nice to allow you to pass in the sandbox name via the --name argument while still using a Sandbox Definition File for other attributes like Sandbox License, Apex Class ID, and Public Group ID. That way, no matter what sandbox name I pass via a command line argument, I can use the same sandbox definition file.
