Implement read-only mode

See original GitHub issue

As part of https://github.com/mozilla/addons-server/issues/1050 we implemented a read-only notification for the API as well.

The behavior is as follows:

In case of a maintainance / read-only mode get’s turned on…

GET requests behave normal
POST, PUT and DELETE requests return 503 with a json response that contains a localized error message
A custom X-AMO-Read-Only header is set to true
a Retry-After header may be set, it’s not a requirement though

In case that maintainance / read-only mode get’s turned off…

GET, POST, PUT, DELETE requests behave normal again
X-AMO-Read-Only header is set to false

Since we’re expecting a maintainance relatively soon it’d be really nice to give this a higher priority, hoping it’s not too much work. But let me know in case it’s more work and needs more time.

I 2nd the @bobsilverberg’s idea of starting with the simplest solution - making sure inline error messages look ok for read-only mode is preferable doing something very specific and involved for such an infrequent use-case.

Given that error messages is updated for 503 responses in case of read-only mode, everything just works already:

There is no need to change anything.

@muffinresearch It looks like @willdurand has answered your question. Doesn’t seem like a huge task.
