Bug description:
  [SRU JUSTIFICATION]

  [Impact]

  Pacemaker fails to start and reports a Library Error as follow :
  "notice: mcp_read_config: 	Configured corosync to accept connections from group 124: Library error (2)"

  [Test Case]

  - Have a corosync/pacemaker cluster with libqb version <=0.16.0.real-1ubuntu4
  - You need sequentially start/stop Corosync/Pacemaker for some amount of times to trigger the issue (until both PIDs of corosync/pacemaker are >99999 and fd >=10 to trigger this issue)

  [Regression Potential]

  The patch is already in place in Debian & Xenial and late Ubuntu
  release version.

  This patch make the description field larger to satisfy all possible
  pids and file descriptor values.

  It has been brought to my attention by a user the following :

  Pacemaker fails to start if its PID is greater than 99999, then it

  from group 124: Library error (2)"
