This commit adds support for the `oidc_oauth_metadata_url` configuration
option. This option specifies the URL of the OIDC server's
metadata endpoint, which contains information about the OIDC server's
endpoints, supported scopes, and other configuration details. By using this
option, we can ensure compatibility with different OIDC servers and reduce
the risk of errors due to manual endpoint configuration.
* Fix typo in managing user account membership with SAML assertion
* Support more config options from Docker env.
* Improve support for SAML key and cert from Docker secrets

Enhancements:
- More robust check when creating self-signed certificates
- Added support for SAML Requested Attributes through "SAML_SP_REQUESTED_ATTRIBUTES" parameter
Problems resolved:
- Method create_self_signed_cert() was invoked nowhere. This puts parameter "SAML_SIGN_REQUEST" description in configs/development.py as incorrect
- Method create_self_signed_cert() was returning error while trying to write out certificate and private key. File handler was opened for writing out TEXT instead of BINARY data
Enhancements:
- Two new parameters are introduced SAML_CERT_FILE and SAML_KEY_FILE. User can now explicitly define own certificate and key file anywhere on file-system.
- If parameters mentioned in previous bullet aren't explicitly defined, in PowerDNS-Admin root directory self-signed certificate will be created.
- Certificates will be used or generated in any case, because in saml.py there are explicit parameters defined which require certificate/key in order to work normally. If they aren't, exception will be thrown. Examples of parameters defined in saml.py requiring certificate: wantAssertionsEncrypted, signMetadata, wantAssertionsSigned.
- Function signatures inside SAML class were fixed
- Redirect URL for /saml/login path was modified (saml_authorized -> index.saml_authorized)
Current status is that SAML metadata can be generated under /saml/metadata and communication to SAML iDP is working
Problems remaining:
- SAML Response doesn't contain any attributes (There is no AttributeStatement on the Response). It can be that problem is on iDP side
- Background thread in retrieve_idp_data() cannot be spawned, this part is currently commented out, old code needs to be revisited
