[Feature]: OCI Provider - Accept Pre-Configured Signer

[gotsysdba]

The Feature

For the OCI Provider, add support for OCI Instance Principal and OKE Workload Identity authentication without adding oci as a dependency. This allows litellm users to authenticate with OCI Generative AI services using cloud-native identity mechanisms instead of API keys.

Motivation, pitch

Currently, litellm's OCI provider only supports user principal authentication (API key + fingerprint + private key). This doesn't work for:

• Applications running on OCI Compute instances (should use Instance Principals)
• Applications running in OKE clusters (should use Workload Identity)
• Security-conscious deployments that want to avoid managing API keys

The OCI SDK provides signers for these auth types, but adding oci as a litellm dependency would be too heavyweight.
