* Alerting: Fix Test Receivers when settings are non-strings
As part of the Alerting extraction, we want to make sure we don't have circular depedencies. As such, I had to move `PostableGrafanaReceiver` to a new struct in `grafana/alerting` called `GrafanaReceiver`.
`PostableGrafanaReceiver` has an attribute called `Settings` that uses a Grafana-propietary struct called `RawMessage`, this struct shadows `json.RawMessage`.
When I created `GrafanaReceiver`, I turned settings into a `map[string]string` thinking all settings would end up as strings. This was a mistake, and this test proves that it doesn't work, and breaks the API.
* (WIP) switch to fork AM, first implementation of the API, generate spec
* get receivers avoiding race conditions
* use latest version of our forked AM, tests
* make linter happy, delete TODO comment
* update number of expected paths to += 2
* delete unused endpoint code, code review comments, tests
* Update pkg/services/ngalert/notifier/alertmanager.go

* clear naming for fields
* shorter variable names in GetReceivers

This commit adds contact point testing to ngalerts via a new API
endpoint. This endpoint accepts JSON containing a list of
receiver configurations which are validated and then tested
with a notification for a test alert. The endpoint returns JSON
for each receiver with a status and error message. It accepts
a configurable timeout via the Request-Timeout header (in seconds)
up to a maximum of 30 seconds.
