QEMU: Rename user network to builtin and update documentation

[spowelljr]

Site:

• Updated references from user to builtin
• Added more information about the differences between the socket_vmnet and builtin network options
• Added install/uninstall instructions for socket_vmnet via brew
• Moved known issues into a tabbed component so user can see issues specific to their network option

QEMU:

• Updated references from user to builtin
• Still supports the user flag, but will rewrite the value to builtin on cluster creation

lets rename the "user" network name to "builtin" to confuse our "user"s (pun intended) less !
and still accept user as a legacy but not advertise it.

Above the Tabbed version of network isssues, we should call it Known Network issue
and we will have different block for Qemu core issues (not network)
