Notify users about the usage of deprecated webhooks (#4898)

* Notify users about the usage of deprecated webhooks

Each time a deprecated webhook is hit, a notification is
created (without duplicating it) to be sent.

* Extend notification to support de-dup and delayed email sent

* Improve decorator to support generic and specific VCS webhook views

* Remove no necessary settings

* DeprecatedWebhookEndpointNotification tests and improvements

* Better docstring

* Lint

* Update copy on notifications for github services deprecation (#5067)

* Updated copy on webhooks

* Drop "deprecated webhook endpoint" copy, this is core team nomenclature, not user
nomenclature.
* Add small amount of docs to point to

* Update docs and point to docs in notification message

* Add year

* Split up deprecated view notification to GitHub and other webhook endpoints (#5083)

* Updated copy on webhooks

* Drop "deprecated webhook endpoint" copy, this is core team nomenclature, not user
nomenclature.
* Add small amount of docs to point to

* Update docs and point to docs in notification message

* Split up deprecated view notification to GitHub and other webhook endpoints

This sets a date for deprecated of these endpoints as Mar 1st 2019. Too
soon?

* Reduce complexity and drop decorator pattern for Notification
  classmethod pattern used in other notifications
* Add notifications for non-GitHub incoming webhooks
* Add docs as well

* More renaming and slight refactor

Found out 2x messages are being generated, so this stops the automated
mechanism for triggering these messages.

* Update dates

* Also update docs

* Typo on date

* Back out some more of the changes to notifications to make them operable without automation

* Add admin method for notification

* Add admin filter for project features

 It might be necessary to re-establish a webhook if you are noticing problems.
 To resync a webhook from Read the Docs, visit the integration detail page and
 follow the directions for re-syncing your repository webhook.
+
+Troubleshooting
+---------------
+
+My project isn't automatically building
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If your project isn't automatically building, you can check your integration on
+Read the Docs to see the payload sent to our servers. If there is no recent
+activity on your Read the Docs project webhook integration, then it's likely
+that your VCS provider is not configured correctly. If there is payload
+information on your Read the Docs project, you might need to verify that your
+versions are configured to build correctly.
+
+Either way, it may help to either resync your webhook intergration (see
+`Resyncing webhooks`_ for information on this process), or set up an entirely
+new webhook intergration.
+
+.. _webhook-github-services:
+
+I was warned I shouldn't use GitHub Services
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Last year, GitHub announced that effective Jan 31st, 2019, GitHub Services will stop
+working [1]_. This means GitHub will stop sending notifications to Read the Docs
+for projects configured with the ``ReadTheDocs`` GitHub Service. If your project
+has been configured on Read the Docs for a long time, you are most likely still
+using this service to automatically build your project on Read the Docs.
+
+In order for your project to continue automatically building, you will need to
+configure your GitHub repository with a new webhook. You can use either a
+connected GitHub account and a :ref:`GitHub webhook integration <webhook-integration-github>`
+on your Read the Docs project, or you can use a
+:ref:`generic webhook integraiton <webhook-integration-generic>` without a connected
+account.
+
+.. [1] https://developer.github.com/changes/2018-04-25-github-services-deprecation/
+
+.. _webhook-deprecated-endpoints:
+
+I was warned that my project won't automatically build after April 1st
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In addition to :ref:`no longer supporting GitHub Services <webhook-github-services>`,
+we have decided to no longer support several other legacy incoming webhook
+endpoints that were used before we introduced project webhook integrations. When
+we introduced our webhook integrations, we added several features and improved
+security for incoming webhooks and these features were not added to our leagcy
+incoming webhooks. New projects have not been able to use our legacy incoming
+webhooks since, however if you have a project that has been established for a
+while, you may still be using these endpoints.
+
+After March 1st, 2019, we will stop accepting incoming webhook notifications for
+these legacy incoming webhooks. Your project will need to be reconfigured and
+have a webhook integration configured, pointing to a new webhook with your VCS
+provider.
+
+In particular, the incoming webhook URLs that will be removed are:
+
+* ``https://readthedocs.org/build``
+* ``https://readthedocs.org/bitbucket``
+* ``https://readthedocs.org/github`` (as noted :ref:`above <webhook-github-services>`)
+* ``https://readthedocs.org/gitlab``
+
+In order to establish a new project webhook integration, :ref:`follow
+the directions for your VCS provider <webhook-creation>`
