man: lvmthin mention alternate syntax

Browse Source 
Users will probably run across the alternate syntax,
so we should explain how it relates to what is used here.

.SS Alternate syntax for specifying type thin\-pool
\&
The fully specified syntax for creating a thin pool LV shown above is:
.B lvconvert \-\-type thin-pool \-\-poolmetadata VG/ThinMetaLV VG/ThinDataLV
An existing LV is converted to a thin pool by changing its type to
thin-pool. An alternate syntax may be used for the same operation:
.B lvconvert \-\-thinpool VG/ThinDataLV \-\-poolmetadata VG/ThinMetaLV
The thin-pool type is inferred by lvm; the --thinpool option is not an
alias for --type thin-pool. The use of the --thinpool option here is
different from the use of the --thinpool option when creating a thin LV,
where it specifies the pool in which the thin LV is created.
.SS Automatic pool metadata LV
\&
A thin data LV can be converted to a thin pool LV without specifying a
thin pool metadata LV. LVM automatically creates a metadata LV from the
same VG.
