[Test]: Add tc for default ping-timeout and epoll thread count
Test Steps: 1. Start glusterd 2. Check ping timeout value in glusterd.vol should be 0 3. Create a test script for epoll thread count 4. Source the test script 5. Fetch the pid of glusterd 6. Check epoll thread count of glusterd should be 1 Change-Id: Ie3bbcb799eb1776004c3db4922d7ee5f5993b100 Signed-off-by: nik-redhat <nladha@redhat.com>
