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.

* Remove inhibited/silenced text
In the alert list, this is already seen via the
icons. In the silence preview, since it's in the
silence preview, clearly it's affected by the
silence.
* Generate assets

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.

Previously the api url was hardcoded in the elm logic fetching the
status of an Alertmanager. Instead it is now being passed down like we
already did for /alerts, /silences and /receivers.

Instead of having one general silence, differentiate between postable
and gettable silence, hence making more fields required.

With the previous patch /status and /silences were requested from api
v2. Requesting alerts from api v1 is done in a separate commit to be
able to revert it once alerts also come from api v2.

This patch makes the Alertmanager UI (/status & /silences) use the
api/v2 endpoint. In addition it adds logic to generate the elm side data
model based on the OpenAPI specification.

Support `w` duration when making silences. Remove
`y` as a supported duration, silences are for
short term notification prevention.

* Use a button instead of a for buttons
Using <a> was causing an unintended redirect to
the root. It appears this behavior has changed in
0.19.

* Wait for the gossip to settle before sending notifications
See #1209 for details.
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`.

* Inconsistent use of baseUrl and apiUrl arguments
Both are Strings, so flipping the order between
one invocation and another didn't raise any
argument from the compiler. The baseUrl argument
is actually unnecessary, and has been removed.
* Update bindata.go
* Render status page without mesh connection (#918)
A mesh connection was assumed, even though the
value that was being passed into the helper
function was a possibly-nil pointer. Add a check
for this, and return a nil value in that case. The
frontend finds this when decoding the json
payload, and displays the "not configured"
message.
* Update bindata
* Test for consecutive chars throughout string
Previously, we were only testing for consecutive
characters at the beginning of the string. Now,
the entire string being compared is searched
through for a matching character, and then the
consecutive search starts.
We were seeing weird situations where the text
entered matched the last half of certain terms,
but because it wasn't, but because we only
searched from the start, results that probably
shouldn't have been the top suggestion were being
suggested too high on the list.
* Weight consecutive matches more highly
Bit of a guess, this seemed to give better results
for my small test case.

When clicking on a label on the AlertList or SilenceList view, the
changed Alert/Silence query is appended to the current url. This Postfix
should not start with a slash. If it does, the url is not appended but
replaced by the browser instead resulting in a `pushState` exception.

Add trailing slash via JS & add routePrefix console param
Add Javascript script tag to `index.html` which adds a trailing slash to
the url pathname if none is present. This is done to ensure assets like
`script.js` are loaded properly.
Example without patch:
If the pathname is "mxinden.com/alertmanager" the browser will try to
download the `script.js` asset from "mxinden.com/script.js". This
request will fail.
Example with patch:
If the pathname is "mxinden.com/alertmanager", Javascript redirects the
browser to "mxinden.com/alertmanager/" and then the `script.js` asset
will be downloaded from "mxinden.com/alertmanager/script.js". This
request will succeed.
Add `-web.route-prefix` as a console parameter. This configures a
Prefix for the internal routes of web endpoints. Defaults to path of
-web.external-url like in *Prometheus*.
Trim slashes off of route prefix and add one slash at the beginning.
Make sure route prefix is not empty or just a slash before prefixing
router.
