Do not send alerts on slow install and make the step fail on < 15% battery.

Do not send alerts on slow install and make the step fail on < 15% battery.

The slow install errors were happening too often causing too many alert emails.
A few bots have had device battery problems. E.g.
http://build.chromium.org/p/chromium.perf/builders/Android%20GN
The device status step will fail when charge is < 15%, allowing devices to
recharge before running more tests on them, and thus avoiding devices turning
off and needing someone to go to the clab to restart the devices.

LGTM. I will TBR this so that we stop the insane number of alerts we are getting
for the slow install speed. Also, we discussed the battery failure. I will
monitor the bots (esp. try bots).

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
