Older LVM code does not play well with the very latest LVM2 configs inside RHEL 7.4

####################################################################

If you use the configuration file from lvm2 >= 2.02.171 with any earlier lvm,
all lvm utilities break with the error:

  Invalid units specification

  This happens because lvm.conf contains a new value: ( Used to default to "h" )

  	# Default value for --units argument.
		units = "r"

		The problem is that older version of LVM do not understand this
		and fail with this error message:

		  Invalid units specification

METHOD #1 
The lvm.conf gets loaded into memory at initialization time.
Editing the file does not change the behavior.  A reboot is required
Commenting or editing that one line and rebooting resolves the issue.

METHOD #2
Replacing our static binary with the new OS version in 7.4
a.) mv /usr/sbin/r1soft/lib/lvm.static /usr/sbin/r1soft/lib/lvm.static.old
b.) ln -s /sbin/lvm /usr/sbin/r1soft/lib/lvm.static
