Modify tempmon server logic to take "unfair" time windows into account
...
when a client or probe first are (re-)enabled, we can't expect to have readings
within the time window we'd normally be checking. previously we'd get false
alarms about "probe error status" etc. when this happened; hopefully no longer!

Add "default" probe timeout logic for server readings check

this way we don't have to set those timeouts on every single probe

Add per-status timeouts and tracking for probe status
...
i.e. this lets us keep track of when a probe becomes "high temp" and then later
if it becomes "critical high temp" we can still know how long it's been high

yikes! first probe whose readings were checked okay, was causing other probes
to just be skipped

i.e. don't generate new "now" when sending an email, just use the "now" we
established when starting to check the readings

Make server more tolerant of database restart
...
note that a retry is *not* attempted within a given "check readings" run.
rather, server will consider that full readings check to have failed, if any
part of it fails.
but then we keep track of type/amount of some (database connection) failures,
and will suppress logging the full error for first 3 attempts. in practice
this lets us recover from simple database restarts, and if database becomes
truly unavailable we'll hear about it shortly.
any other type of error is immediately logged on first failure.

Tweak server logic for checking client readings
...
do not check readings for "archived" clients. do not consider the client
"offline" unless it has *no* current probe readings. previously we were
assuming offline if any probe readings were missing, even if some were found.
