package clouds provides a parser for OpenStack credentials stored in a clouds.yaml file.

NewProviderClient logs in to an OpenStack cloud found at the identity endpoint specified by the options, acquires a token, and returns a Provider Client instance that's ready to operate.

WithHTTPClient enables passing a custom http.Client to be used in the ProviderClient for authentication and for any further call, for example when using a ServiceClient derived from this ProviderClient.

WithTLSConfig replaces the Transport of the default HTTP client (or of the HTTP client passed with WithHTTPClient) with a RoundTripper containing the given TLS config.
