Handle cgts-client calls for non-admin users

Handle http client exceptions for non-admin
users. This is because some alarms/events
metadata are not available for them.

For example if the call fails the user will see the a
value like:

"host=controller-1.port=enp0s8"

instead of:

"host=controller-1.port=0cbb441a-874d-418e-bd57-7aa1b8ab0044"

Before this if an error in translation happened, the user
experienced an alert badge saying "Unable to retrieve
Events", then the user seen an empty table.
