[TerminalChat/AI; Enterprise] Company wide predefine lm provider parameter

[htcfreek]

Description of the new feature

Add a second group policy to set the required ChatAI/LM provider parameters like endpoint uri, api key, and so on.

Use case

That a company can push the configuration to their clients instead of telling (mail or documentation) their users how to configure the provider. This is especially useful if all people should use the same (local/on premise) LM provider infrastructure.

Implementation notes

• String policy accepting a json value in one line.
• Maybe not possible because of the encryption of the api key(s).
• Maybe a second policy for the provider that is enabled by default.
• Possible json format:

{
  "defaultEnabledProvider": "lm-provider-id",
  "lm-provider-id": [
    "property": "value",
    "property": "value"
  ],
  "lm-provider-id2": [
    "property": "value",
    "property": "value"
  ]
}
