Web UI: user can not create services

[Timur Nurlygayanov]

Steps To Reproduce:
1. Install OpenStack from devstack
2. Install Murano dashboard by the documentation on murano.mirantis.com
3. Restart apache service:
{code}sudo service apache2 restart{code}
4. Login to default OpenStack Horizon WebUI
5. Navigate to Project > Environments
6. Create new environment 'test'
7. Navigate to the list of services and create new service (for example, AD service)

Observed Result:
User can not create new services. Looks like it can be problem with sessions handling configuration.
Please see attached video file for more detailed information.
