ANYSec padlock label to identify the selected service

[tiago-amado]

The MACSec padlock displays the encrypted counters for the port (all services).
The ANYSec padlock, however, displays the encrypted counters per service.
To change or view the selected service, we must look to the dropdown on the top. Its is not intuitive and could be misleading for the users when they look to the padlock.
Idea is to add a label to the ANYSec padlock to show the selected service.
The Macsec padlock can also have a label stating it is showing counters for all services.

@tiago-amado analyzing the metrics received from the encryption group, there is no relationship between the service in the exposed metrics, however, since there is a map of a encryption group by services, this value can be used instead, but this leads to an issue that I had not noticed, basically the change for some reason is not immediate, forcing the screen to be refreshed so then you can see that changed, you can try it in the svc-labels branch, and let me know your thoughts.

A PR has been submitted, adding sum stats for encryp/decrypt packet to be alligned with macsec stats at edge.

Already tested and approved, its perfect.
Note: MACSec is always enable and the counters shows the sum of all running services. The ANYSec show the sum of all running services with ANYSec enabled.
The counters will be aligned if ANYSEc is enabled for the running services. If we disable it we'll notice distinct counters.
