This moves a single try bot host to be used as a experimental 10% CQ bot that
will be on N5's.

This will allow us to test in preperation for switching completely to N5's for
the CQ and main waterfall.

Here is the config.json CL for it:

IMHO there is no need to do this, but leaving the final decision up to you.

My recommendation is _not_ to do this, but I'm fine either way.

Pawel, can you provide more explanation as to why that is your recommendation.
We currently have an fyi tester here:
http://build.chromium.org/p/chromium.fyi/builders/Android%20Tests%20%28N5%29%...

Are you suggesting that that is enough? If so, I disagree and I'd prefer to land
this as a 10% CQ bot. Just the CL alone allowed jbudorick to point out we want
to test on a releast bot rather than debub
(https://codereview.chromium.org/980413003). I'd feel better to have it at least
on 10% before making the big switch from N4's to N5's.

If you have a better suggestion to providing confidence that move will go
smoothly, please let me know. Thanks.

Oops, I didn't realize this slave has different hardware than any of the
existing pools. Sorry for the confusion, this looks good.

A revert of this CL (patchset #4 id:60001) has been created in
https://codereview.chromium.org/1025673003/ by navabi@google.com.

The reason for reverting is: CQ bot did it's job and then we moved everything to
N5's. Now it's time to return this bot to the original CQ fleet..
