Dot-Source Cluster Name

Dot-Source the process to gather the cluster name and check it against a
regex.
Move Create-VSAN variables from ucs-build

Move the create-VSAN variable request from ucs-build into create-vsans.
This will facilitate modules becoming more independent.

If cluster is virtual, poll user for vsan names/numbers; else, ignore.
Off-load PC variables to vsan-pc-[ab]-up

Make port channel variables on vsan-pc-a-up and vsan-pc-b-up more
indepedent of the ucs-build script. Prompt for non-standard build,
reject if yes.

Add nominal support for pirate speak.
Move vsan-port-add into vsan-pc-a-up

Consolidate vsan activities. Since the three separate activities of VSAN
PC creating, enabling, and adding ports are always performed together,
chainload those scripts
Remove Redundant Line

Dot-source calling vsan-pc-port-add is actually identical to create-pc,
which is already called. Remove this line.
Move SP Creation Out of bind-vhba

SP Creation for Virtual is still supported, moved to its own file
Dot-Source New SP Creation File
