Horizon fail to load resources usage if ceilometer configured with SSL

[zhu zhu]

When ceilometer is configured in SSL, within Horizon configured as below for the local_setting

OPENSTACK_SSL_CACERT=<cert>
OPENSTACK_SSL_NO_VERIFY=false

Horizon fail to load the meter-list from ceilometer while ceilometer will get the meter-list with the same cert via command line.

With checking the code of Horizon. Found that, It uses the wrong arguments to pass the cacert: It should be 'cacert' instead of 'ca_file'

In openstack_dashboard/api/ceilometer.py:
@memoized
def ceilometerclient(request):
    """Initialization of Ceilometer client."""

    endpoint = base.url_for(request, 'metering')
    insecure = getattr(settings, 'OPENSTACK_SSL_NO_VERIFY', False)
    cacert = getattr(settings, 'OPENSTACK_SSL_CACERT', None)
    return ceilometer_client.Client('2', endpoint,
                                    token=(lambda: request.user.token.id),
                                    insecure=insecure,
                                    ca_file=cacert)

This prevents Horizon from connecting to ceilometer via a secure connection.

    Fix incorrect ca arguments for calling ceilometer client

    With ceilometer configured with SSL, Horizon fail to connect to
    ceilometer to load the meters(usage data) due to it passed a wrong
    of ca argument for ceilometer client. Should use 'cacert' instead
    of 'ca_file'.
