any reason why not CYPRESS_NO_COMMAND_LOG instead of CYPRESS_NO_COMMANDLOG? the lack of space seems arbitrary

[kuceb]

@flotwig it's arbitrary. I'll change it

[flotwig]

It's simply so beautiful

[flotwig]

LGTM, but I think @bkucera should you add a section to the troubleshooting doc for this? or, what is the documentation plan?
