* 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`.
* cluster: fix typos and base interval on gossipInterval
See #1223, looks like OpsGenie now sometimes returns a 422 when you
don't specify a team. This change cleans up the JSON output and
add a few unit tests.
After the initial notification has been sent, AlertManager shouldn't notify the
receiver again when no new alerts have been added to the group during
group_interval.
This change also modifies the acceptance test framework to assert that no
notification has been received in a given interval.

The PagerDuty Events API (v1), used by integrations with monitoring tools, will continue to be supported. There are currently no plans to deprecate, end support for or sunset it.
The end-of-support notice cited in the log message removed applies only to the *REST API* version 1, which PagerDuty will no longer support as of February 2018, but which Prometheus does not use.
* Template Source field in pagerduty payload
As a sane default we link to alertmanager, but
leave templating available to the user if
something suits their system better.
* Don't send parts with empty templates.
* Add a MIME-Version: 1.0 header.
* Place text/html part last, as parts are supposed to be in increasing preference order.
* added email notification text content support (configuration text)
added default email notification text content default value empty
converted email notification from html to multipart/alternatives with support to both html (first) and text (last)
ignore intellij IDE .idea working folder
* removed specific editor .gitignore entries
* renamed TEXT to Text as it's not an acronym
added TODO note to refactor multipart code to use standard go library
* refactored to use standard go mime/multipart library for text and html parts and bounderies
* use multipart createPart returned writer
added error handling while creating parts
removed unnecessary quotes from boundry string
* removed unnecessary comments
* Support for custom SMTP hello string
Some MTAs insist that they be greeted with a fully qualified domain
name. The default provided by the net/smtp library, "HELLO localhost",
is not sufficient and will result in rejected messages.
This changeset adds a new configuration option that allows the
alertmanager to do its job in such an environment.
* Test SMTPHello parsing
