testing flask gnmi timeout

[hellt]

if you run

docker exec client7 bash /config/install_gnmic.sh

in this branch you will see the error

[alfilipe]

The flask app have been changed to fix the issue with unavailable connections, it will try to connect every 10 seconds (the amount of seconds can be changed on the flask app under the function '__init__' of the class 'Telemetry').
The file "install_gnmic.sh" has been changed to allow the flask app stdout and stderr to be writen on the docker logs.

while the nodes are not reachable you will see some messages like those bellow:

[Flask] - sub_telemetry - unable to connect to the host pe1 will try agrain in 10 seconds
[Flask] - update_anysec_status - unable to connect to the host pe1 will try agrain in 10 seconds
[Flask] - update_port_status - unable to connect to the host p3 will try agrain in 10 seconds

while the node is available and an GNMI connection can be established but the GNMI path is not accessible yet, can be exepted the see some exception errors link the one bellow:

Exception in thread Thread-320:

after that the all will run as it is supposed to be.

We need to uncomment nodes from yml file. Those were commented only for tests.

[tiago-amado]

@alfilipe, we need to merge your code into the main. this branch was created for test proposes and there are changes in the yml file that must be reverted. Either we do that or we create a new clean branch and deploy the changes again.
@hellt, how do you suggest to proceed?

[hellt]

@tiago-amado I don't think we need to proceed with this now
The repo works from the main branch, @aaakpinar please confirm if that is the case and you don't have local changes that were not pushed to the repo.

As far as the future state of the automation panel is concerned, @siva19susi is almost done with the refactored versiont that we will use later in favor of the current python version.
