Currently to add a new provider to an existing config.hcl you need to manually add the provider config block

Describe the solution you'd like

If running cloudquery init [new provider] check if config already contains said provider, and if not appends the relevant config block to the config.hcl in the same way running cloudquery init aws gcp okta will append them in sequence for a new config.hcl file
