Updating Cops ManageIQ/guides#338

@jrafanie can you look into this issue

[juliancheal]

@chessbyte @jrafanie I think the last few issues from stopping us updating to 5.2 is ManageIQ/activerecord-virtual_attributes#39

[djberg96]

@juliancheal, @jrafanie Is this done?

[jrafanie]

No, I believe the only thing left was in activerecord virtual attributes. @kbrock do you know where we stand there with 5.2 support? Are we ready to try to get master on that?

[kbrock]

Sigh, I've been dragging.

Think it requires a pre 5.1 version, a 5.2 version, and a 6.0 version.

I need to get back to this

[kbrock]

Ok, I got that one pesky test passing for 5.2 ==> ManageIQ/activerecord-virtual_attributes#62

Lets see how those cross repo tests work, then we'll continue on the miq issues
