* Alerting: Persist notification log and silences to the database
This removes the dependency of having persistent disk to run grafana alerting. Instead of regularly flushing the notification log and silences to disk we now flush the binary content of those files to the database encoded as a base64 string.

* Change templateCaptureValue to support using template functions
This commit changes templateCaptureValue to use float64 for the value
instead of *float64. This change means that annotations and labels can
use the float64 value with functions such as printf and avoid having to
check for nil. It also means that absent values are now printed as 0.
* Use math.NaN() instead of 0 for absent value
Fix region annotations not displayed correctly when returning timeend column
as epoch timestamp and by that making sure that the returned data frame field
named timeend is treated as time type.

* Alerting: Fix alert flapping in the alertmanager
fixes a bug that caused Alerts that are evaluated at low intervals (sub 1 minute), to flap in the Alertmanager.
Mostly due to a combination of `EndsAt` and resend delay.
The Alertmanager uses `EndsAt` as a heuristic to know whenever it should resolve a firing alert, in the case that it hasn't heard
back from the alert generation system.
Because grafana sent the alert with an `EndsAt` which is equal to the `For` of the alert itself,
and we had a hard-coded 1 minute re-send delay (only applicable to firing alerts) this meant that a firing alert would resolve in the Alertmanager before we re-notify that it still firing.
This commit, increases the `EndsAt` by 3x the the resend delay or alert interval (depending on which one is higher). The resendDelay has been decreased to 30 seconds.
