Advice for "lifecycle"

[julian-cable]

From @rclee33: The RHT style guide says to write "lifecycle" as one word (https://stylepedia.net/style/6.2/#l). However, several product names use the 2-word form: "Red Hat Enterprise Linux Extended Life Cycle Support Add-On". To avoid possible confusion, I'm wondering whether we should add a sentence to the Style Guide entry about the exceptions in product names.

Julian: I think a suitable approach here would be to use one word by default, but two words if referring to a product name that writes it that way.

Word Nerds has an open item about how to write the term, and has not yet made a decision. You can see their notes here: https://docs.google.com/document/d/10uOb9Psvh4LWatH-B3raiSwbBsO_4tMFiQkfbedxMmk/edit#heading=h.jmpvkofa6wr
