This commit fixes a bug where an invalid silence causes incomplete
updates of existing silences. This is fixed moving validation
out of the setSilence method and putting it at the start of the
Set method instead.

This commit adds a unit test for the postSilencesHandler to
create and then update a silence. It shows that changing the
ID of an existing silence returns 404 Not Found, and removing
the ID of an existing silence re-creates that silence with
a different ID.

* Fix MaxSilences limit causes incomplete updates of existing silences
This commit fixes a bug where the MaxSilences limit can cause an
incomplete update of existing silences, where the old silence can
be expired but the new silence cannot be created because it would
exceeded the maximum number of silences.

* Rename matchers package to matcher singular
I realized that we had named the package plural "matchers" when
its idiomatic in Go to use singular package names.

This commit removes the Id from the method silences.Set(*pb.Silence)
as it is redundant. The Id is still set even when creating a silence
fails. This will be fixed in a later change.

* Silence limits as functions
This commit changes silence limits from a struct of ints to a struct
of functions that return individual limits. This allows limits
to be lazy-loaded and updated without having to call silences.New().

This commit fixes silence tests that relied on the maintenance
function running at a fixed 100ms interval. If the go runtime
that runs the maintenance is not scheduled with 150ms then the
test will fail.

* Fix race condition in dispatch.go
This commit fixes a race condition in dispatch.go that would cause
a firing alert to be deleted from the aggregation group when instead
it should have been flushed.
The root cause is a race condition that can occur when dispatch.go
deletes resolved alerts from the aggregation group following a
successful notification. If a firing alert with the same
fingerprint is added back to the aggregation group at the same time
then the firing alert can be deleted.
