Fix redirection after sign in when using auto_sign_in_with_provider

Logic for redirect path moved to a filter. This allows it to run properly when the auto_sign_in_with_provider filter takes control.

Workaround the insecure password warnings emitted by MySQL 5.6

When using MySQL 5.6, the following output is emitted every time a backup is created, even with CRON=1.

```
Warning: Using a password on the command line interface can be insecure.
```

This fix works around that by sending the password via the [`MYSQL_PWD`](http://dev.mysql.com/doc/refman/5.6/en/environment-variables.html) environment variable.

Fix for #9527

Update Flowdock integration to support new Flowdock API

Requires that users create a Git source in their flows and update the configured token to the Git source token. The old flow tokens can't be used.

Disable internal issue tracker if external tracker in use

### What does this MR do?

This MR disables routes to the internal issue tracker if an external issue tracker (e.g. Redmine) is in use. A 404 page is returned if a user attempts to access any of the issue routes.

### Why was this MR needed?

Enabling the external issue tracker would still keep the internal one active, which would lead to odd behavior where users could create issues but not close them.

### What are the relevant issue numbers?

Closes #2006

See merge request !993
