Keycloak support

Keycloak support

launchpad blueprint: https://blueprints.launchpad.net/vitrage/+spec/keycloak-support

As part of an on going effort to make vitrage to be able to work also in a non OpenStack environment (in addition to the default OpenStack environment). We should be able to make vitrage work with a different authorization server instead of keystone. An optional authorization server can be Keycloak which is an open source Identity and Access Management solution aimed at modern applications and services

Problem description

Vitrage at the moment can only work in an OpenStack environment because it needs Keystone for authorization. We should support other authorization such as Keycloak.

Proposed change

New auth_mode in api section in Vitrage config file:

[api]
auth_mode = keycloak

New keycloak section with the auth_url in Vitrage config:

[keycloak]
auth_url = http://[keycloak server]:[keycloak port]/auth

The Vitrage server will use a new middleware which will authenticate with the Keycloak server once an api request is received.

A new auth plugin will be added to the vitrage client which will get the token from the Keycloak server and sent it with the api request.
