Add another header so client SDKs can identify their versions which can be used for immediate detection of possible compatibility issues. A semver mismatch against the wrong server should be immediately flagged and requests should be denied. Also change `X-LlamaStack-ProviderData` to `X-LlamaStack-Provider-Data` since that hyphenation is better.
