New API: lvm_scan, deprecate vgscan (RHBZ#1602353).

Browse Source 
The old vgscan API literally ran vgscan.  When we switched to using
lvmetad (in commit dd162d2cd5) this
stopped working because lvmetad now ignores plain *scan commands
without the --cache option.

We documented that vgscan would rescan PVs, VGs and LVs, but without
activating them.

I have introduced a new API (lvm_scan) which scans or rescans PVs, VGs
and LVs.  It has an optional activate parameter allowing activation of
any new LVs that are found.

With lvmetad this nicely maps to the single command:

 pvscan --cache [--activate ay]
