Provide default config values

[ryanmerolle]

The following config values should have default config:

        # Default transport method, [tfp|http]
        "DEFAULT_TRANSFER_METHOD": "http",
        # Log file
        "UPGRADE_LOG_FILE": "/var/log/upgrade.log",
        # Queue name. Check step 1 (dockerfile). Should be the same
        "UPGRADE_QUEUE": "software_manager",
        # Custom field name which is used for store current SW version
        "CF_NAME_SW_VERSION": "sw_version",
        # folder name for image storing. located in netbox media.
        "IMAGE_FOLDER": "software-images",
        # Threshold for non-ACK check
        "UPGRADE_THRESHOLD": 2,
        # Number of tries to connect to device before declare that we lost it.
        "UPGRADE_MAX_ATTEMPTS_AFTER_RELOAD": 10,
        # Hold timer between tries
        "UPGRADE_SECONDS_BETWEEN_ATTEMPTS": 60,
