[Halld-offline] Running GlueX software in a container

[Mark Ito]

Sean,

Sounds like you saw that there are actually three HOWTOs in that section 
of the HOWTO page. So those were essentially existence proofs of various 
ways to get to GCC 8. I wrote the HOWTOs in large part to document what 
I had learned about each case. Recall that GCC 8 was chosen because it 
is the compiler version associated with RHEL/CentOS 8. All of those 
HOWTOs probably need update. As I said at the meeting we should try to 
minimize the number of ways-to-8 that we propose to the collaboration, 
hopefully the one and true way-to-8.
