This PR is a fix for #498.
It introduce three different methods to get the self container ID, two based on reading from different files in
/procand one using the Docker API via the container mounted socket. The three methods are tried in order and theget_self_cid()output an error if none of them gave what seems to be a correct Docker container ID (ie a 64 characters long string).
