Use DCM as dmon fileserver

[LordJavi]

• Use DCM for store and download files requested by dmon
• Generate dynamically version.txt. Values stored in config file, could be edited from settings page

Example with CURL:

curl -s -X POST -d '{"uuid": "YOURUUID"}' -H 'authorization: bearer YOURGCKEY' -H 'Content-Type: application/json' -O --output-dir /var/root https://YOURDCMURL/api/download/pogo.deb
