Instead of keeping all notifiers in the notify package, it splits them
into individual sub-packages. This improves readability and

If a users chooses to disable the Alertmanager cluster feature, there is
no cluster name nor cluster peers. Hence these should be optional. Only
cluster status is set to "disabled".

When users start Alertmanager with `--cluster.listen-address=`, the
cluster will not be initialized, hence api.peer will be `nil`. So far
this would result in a nil pointer dereference by the API v2 accessing
the api.peer field.
With this patch, api v2 skips populating the peers array, sets the name
to an empty string and the status to "disabled" in case `api.peer` is
nil.

With issue 1465 on openapi-generator [1] being fixed, we can not extract
shared properties of the gettable and postable alert definition into a
shared object (`alert`) like we do for silence, gettable silence and
postable silence.
In addition this patch does the following changes to the UI:
- Use `List GettableAlert` instead of plural type definition like
`GettableAlerts` because the plural definitions are not generated.
- Fix openapi-generator-cli docker image to specific hash.

Instead of only testing single instance Alertmanagers, this patch
enables individual tests to spin up Alertmanager clusters.
In addition it adds two tests:
1. A test firing alerts against a cluster, expecting to only receive a a
notification by one of the Alertmanager instances in the cluster.
2. A test firing alerts both against a single instance as well as a
cluster, making sure the output equals.

The current Alertmanager API v1 is undocumented and written by hand.
This patch introduces a new Alertmanager API - v2. The API is fully
generated via an OpenAPI 2.0 [1] specification (see
`api/v2/openapi.yaml`) with the exception of the http handlers itself.
Pros:
- Generated server code
- Ability to generate clients in all major languages
(Go, Java, JS, Python, Ruby, Haskell, *elm* [3] ...)
- Strict contract (OpenAPI spec) between server and clients.
- Instant feedback on frontend-breaking changes, due to strictly
typed frontend language elm.
- Generated documentation (See Alertmanager online Swagger UI [4])
Cons:
- Dependency on open api ecosystem including go-swagger [2]
In addition this patch includes the following changes.
- README.md: Add API section
- test: Duplicate acceptance test to API v1 & API v2 version
The Alertmanager acceptance test framework has a decent test coverage
on the Alertmanager API. Introducing the Alertmanager API v2 does not go
hand in hand with deprecating API v1. They should live alongside each
other for a couple of minor Alertmanager versions.
Instead of porting the acceptance test framework to use the new API v2,
this patch duplicates the acceptance tests, one using the API v1, the
other API v2.
Once API v1 is removed we can simply remove `test/with_api_v1` and bring
`test/with_api_v2` to `test/`.

* notify: notify resolved alerts properly
The PR #1205 while fixing an existing issue introduced another bug when
the send_resolved flag of the integration is set to true.
With send_resolved set to false, the semantics remain the same:
AlertManager generates a notification when new firing alerts are added
to the alert group. The notification only carries firing alerts.
With send_resolved set to true, AlertManager generates a notification
when new firing or resolved alerts are added to the alert group. The
notification carries both the firing and resolved notifications.

* Update old alert with result of merge with new
On ingest, alerts with matching fingerprints are
merged if the new alert's start and end times
overlap with the old alert's.
The merge creates a new alert, which is then
updated in the internal alert store.
The original alert is not updated (because merge
creates a copy), so it is never marked as resolved
in the inhibitor's reference to it.
The code within the inhibitor relies on skipping
over resolved alerts, but because the old alert is
never updated it is never marked as resolved. Thus
it continues to inhibit other alerts until it is
cleaned up by the internal GC.
This commit updates the struct of the old alert
with the result of the merge with the new alert.
An alternative would be to always update the
inhibitor's internal cache of alerts regardless of
an alert's resolve status.

* Update inhibitor cache even if alert is resolved
This seems like a better choice than the previous
commit. I think it is more sane to have the
inhibitor update its own cache, rather than having
one of its pointers updated externally.

And move API client code to its own package.
* cli: remove unused structs
When the aggregation group receives an alert that is past the initial
group_wait value, it should reset its timer only if the timer has ever
expired. Otherwise it means that the flush is already in-progress.
* cli: extract client bindings of the v1 API from amtool
This is a continuation of [1] but the code is kept in the alertmanage
repository rather than having it in client_golang.

As an heuristic for mesh readyness, try to see if
the mesh looks stable (the number of peers isn't changing too much).
This implementation always mark the altermanager as ready after a maximum of 60s.
This adds one new flags to control this behavior:
```
--cluster.settle-timeout=60s mesh settling timeout. Do not wait more than this duration on startup.
```
It also adds `/-/ready` which always return 200 (in order to make it clear
that we are ready as soon as we can receive requests).
The mesh status is exposed in `/api/v1/status` and visible on `/#/status`.
