Add new search options for security service

We can filter security services only by status, name, id and type now.

Add new search options:
    user,
    server,
    dns_ip,
    domain
to _get_security_services in SecurityServiceController to be able to filter
security services by these fields.

Allow filtering security services by share network id.

Add information about share networks to result if 'detailed' mode enabled.

Add unit and tempest tests for filtering security services.

Implements bp improve-security-service-list-filtering
