Description of problem:


    BEFORE:

    posixlk.posixlk[0](ACTIVE)=type=WRITE, whence=0, start=0, len=0,
    pid = 13635, owner=2dd2c3a11706dc8c, client=0x7f159012b000,
    connection-id=(null), granted at 2018-12-31 14:20:42

    AFTER:

    posixlk.posixlk[0](ACTIVE)=type=WRITE, whence=0, start=0, len=0,
    pid = 10977, owner=b485e33df21bdaa2, client=0x7fa24c01ab90,
    connection-id=CTX_ID:68e12340-eed2-4386-bf5e-1f43cf8693d9-GRAPH_ID:0-
    PID:10901-HOST:dhcp35-215.lab.eng.blr.redhat.com-PC_NAME:patchy-client-0-
    RECON_NO:-0, granted at 2018-12-31 14:33:50


Printing the connection id helps figure which host the client is running on and
what it's pid is. This information was found to be lacking in one of the bzs
where there was a deadlock in containerized workload due to lock not released
posisbly by heketi and the client could not be easily located due to missing
conn id info.
