This PR introduces two new features - AWS STS compatible STS API named AssumeRoleWithClientGrants ``` POST /?Action=AssumeRoleWithClientGrants&Token=<jwt> ``` This API endpoint returns temporary access credentials, access tokens signature types supported by this API - RSA keys - ECDSA keys Fetches the required public key from the JWKS endpoints, provides them as rsa or ecdsa public keys. - External policy engine support, in this case OPA policy engine - Credentials are stored on disks
