When generating OpenStack API query URLs for dynamic pollsters,
Ceilometer uses urllib.parse.urljoin to append url_path to the
endpoint URL.
If an API endpoint URL returned by Keystone does not have a
trailing slash and the specified url_path value is a relative
path (e.g. does not start with /), urljoin will replace the
final segment of the base URL instead of appending url_path to it.
This breaks generating links in dynamic pollsters for OpenStack services
if the endpoint URL in the Keystone service catalog does not have a trailing
slash. This is particularly relevant for OpenStack services that incorporate
the project ID into the API endpoint URL, such as Trove as shown below.
>>> urljoin("http://example.com:8779/v1.0/12345678", "mgmt/instances")
'http://example.com:8779/v1.0/mgmt/instances'
If there is a trailing slash on the end of the base URL,
url_path will be appended to the end of the URL as expected.
>>> urljoin("http://example.com:8779/v1.0/12345678/", "mgmt/instances")
'http://example.com:8779/v1.0/12345678/mgmt/instances'
This commit changes the behaviour of the dynamic pollster URL joins
by making sure there is a trailing slash on the endpoint URLs when
appending the defined url_path to them.
This may break existing dynamic pollster configurations that rely
on this behaviour, but given that most OpenStack services probably
wouldn't, there shouldn't be too many changes that would be required.
