Description

With the testing of large stripe count with the lustre test suite creating a list of OSTDEV and oss host can become very large so to simply this I implement pdsh HOSTLIST for the test suite configuration file. For example instead of ost1_HOST=foo1;ost2_HOST=foo2,etc you can do a simple ost_HOST=${ost_HOST:"foo[1-n]"}. Also with the power of HOSTLIST combos like ost_HOST=${ost_HOST:"foo[1-3,4,9-20]"} are possible. Many forms of HOSTLIST have been tested in our test beds. Can be expanded later to devices as well as host.
