vendor-data is not being implemented when it is added via config-flags

[Ebrar Leblebici]

When we add new config-flags to nova configuration in nova-cloud-controller by running "juju config nova-cloud-controller config-flags="vendordata_providers=StaticJSON","vendordata_jsonfile_path=/etc/nova/vendor_data.json", normally it should also change the nova configuration file in nova-compute node. But it does not and that is why the instance not able to get the vendor-data.

When I change the configuration by using this "vendor-data" option via the command below;

juju config nova-cloud-controller vendor-data='{"cloud-init": "#cloud-config
 timezone: Europe/Istanbul"}'

vendor_data.json file got the content that I gave with the command and it also changed both the configuration files in nova-cloud-controller and nova-compute units. So, it has worked.

Charm revisions are:
