Log initialization

[ReliableLion]

After this commit 62f83d6 the sdn-do is not able to create and initialize a log file. I tried to move the load_configuration() method back to the config.py and it worked.

@ReliableLion: Is this issue still open?

[ReliableLion]

Yes, I would correct the issue but I don't know the reason for moving the log init into main.py.
I tried the above fix locally.

Have you tried to ask suggestions @gabrielecastellano or @rbrtbnfgl ?

[rbrtbnfgl]

Did it drop some exceptions calling that method?

[gabrielecastellano]

Do you have the same problem also in the frog4-orchestrator?

[ReliableLion]

No there are no exceptions.
No, the frog4-orchestrator is able to init and print the log.

[gabrielecastellano]

However the code is the same in both repository. Could you check your configuration file (log section), comparing it with the frog-orchestrator one?

[ReliableLion]

The log sections are the same. I also checked that the log file variable is correctly retrieved by the SDN-DO
