search_api 8.x-1.8

This is release 1.8 of the Search API module, containing several bug fixes and new features.

There are some known problems present in this release for which we could use input or advice, if you are interested in seeing them resolved:

• If you are using the Workflows module which is now in Core, see #2956093: Integrate with the Workflows module for properly supporting it in the Search API.
• If you are using complex node access mechanisms (like the view_unpublished module), please take a look at our node access issues. Especially #2948707: ContentAccess processor fails to account for all grant records could use some tesing (even with normal node access) to make sure it doesn't break anyone's access mechanism.
• If you are familiar with Core's REST modules or, even better, entity REST tests, we would be very grateful if you could help us finish #2929603: Add tests for REST support of our entities.
