Subject: [PATCH] LU-3738 tests: improve posix.sh to support BASELINE_FS=zfs

This patch improves posix.sh to support BASELINE_FS=zfs. It also
adds create_zpool(), create_zfs() and destroy_zpool() common
functions into test-framework.sh.

Test-Parameters: envdefinitions=SLOW=yes \
mdtfilesystemtype=zfs mdsfilesystemtype=zfs ostfilesystemtype=zfs \
ostcount=2 testlist=posix
