[COMAC-174] CDN-Local code refactoring - only possible to use SRIOV

- remove unnecessary values in values.yaml
- use camel case
- rename nginx-rtmp to nginx
- allow CDN-Local to use multiple CDN-Remotes
- pull all videos from all CDN-Remotes
- define Roles, RoleBinding, ServiceAccount
- split each POD yaml file into Service, ConfigMap, and StatefulSet
- Remove hard coded values in Service, ConfigMap, and StatefulSet and
then locate them to values.yaml
