Example:
```
collections:
/podcast/:
permalink: /{slug}/
```
- the name of the collection is remembered as `routerName` (in the case above: "podcast")
- the name of the collection is important for two things
1. context value
2. template name
- the context value is available for specific theme helpers e.g. is helper, body_class helper
- we auto-lookup the collection name in your theme e.g. podcast.hbs
- this logic does not apply to static routes
- if you define templates on your collection, they are stronger than the collection name
closes#9675
- with dynamic routing we have introduced a breaking change, which we have overseen
- Ghost does not return absolute urls, that's why the clients need to concat the blog url and the resource url
- with 1.24.0 Ghost returned resource urls including the subdirectory
- this caused trouble for e.g. zapier or the preview feature in the admin client
- revert breaking change and ensure we only expose resource urls without subdirectory

### Dynamic Routing
This is the beta version of dynamic routing.
- we had a initial implementation of "channels" available in the codebase
- we have removed and moved this implementation
- there is now a centralised place for dynamic routing - server/services/routing
- each routing component is represented by a router type e.g. collections, routes, static pages, taxonomies, rss, preview of posts
- keep as much as possible logic of routing helpers, middlewares and controllers
- ensure test coverage
- connect all the things together
- yaml file + validation
- routing + routers
- url service
- sitemaps
- url access
- deeper implementation of yaml validations
- e.g. hard require slashes
- ensure routing hierarchy/order
- e.g. you enable the subscriber app
- you have a custom static page, which lives under the same slug /subscribe
- static pages are stronger than apps
- e.g. the first collection owns the post it has filtered
- a post cannot live in two collections
- ensure apps are still working and hook into the routers layer (or better said: and register in the routing service)
- put as much as possible comments to the code base for better understanding
- ensure a clean debug log
- ensure we can unmount routes
- e.g. you have a collection permalink of /:slug/ represented by {globals.permalink}
- and you change the permalink in the admin to dated permalink
- the express route get's refreshed from /:slug/ to /:year/:month/:day/:slug/
- unmount without server restart, yey
- ensure we are backwards compatible
- e.g. render home.hbs for collection index if collection route is /
- ensure you can access your configured permalink from the settings table with {globals.permalink}
### Render 503 if url service did not finish
- return 503 if the url service has not finished generating the resource urls
### Rewrite sitemaps
- we have rewritten the sitemaps "service", because the url generator does no longer happen on runtime
- we generate all urls on bootstrap
- the sitemaps service will consume created resource and router urls
- these urls will be shown on the xml pages
- we listen on url events
- we listen on router events
- we no longer have to fetch the resources, which is nice
- the urlservice pre-fetches resources and emits their urls
- the urlservice is the only component who knows which urls are valid
- i made some ES6 adaptions
- we keep the caching logic -> only regenerate xml if there is a change
- updated tests
- checked test coverage (100%)
### Re-work usage of Url utility
- replace all usages of `urlService.utils.urlFor` by `urlService.getByResourceId`
- only for resources e.g. post, author, tag
- this is important, because with dynamic routing we no longer create static urls based on the settings permalink on runtime
- adapt url utility
- adapt tests
no issue
This PR adds the server side logic for multiple authors. This adds the ability to add multiple authors per post. We keep and support single authors (maybe till the next major - this is still in discussion)
### key notes
- `authors` are not fetched by default, only if we need them
- the migration script iterates over all posts and figures out if an author_id is valid and exists (in master we can add invalid author_id's) and then adds the relation (falls back to owner if invalid)
- ~~i had to push a fork of bookshelf to npm because we currently can't bump bookshelf + the two bugs i discovered are anyway not yet merged (https://github.com/kirrg001/bookshelf/commits/master)~~ replaced by new bookshelf release
- the implementation of single & multiple authors lives in a single place (introduction of a new concept: model relation)
- if you destroy an author, we keep the behaviour for now -> remove all posts where the primary author id matches. furthermore, remove all relations in posts_authors (e.g. secondary author)
- we make re-use of the `excludeAttrs` concept which was invented in the contributors PR (to protect editing authors as author/contributor role) -> i've added a clear todo that we need a logic to make a diff of the target relation -> both for tags and authors
- `authors` helper available (same as `tags` helper)
- `primary_author` computed field available
- `primary_author` functionality available (same as `primary_tag` e.g. permalinks, prev/next helper etc)

- i am not super happy about `const imageLib = require('../lib/image')`
- i don't really like the name `imageLib`
- but i had no better idea 😃
- if we use the same name in the whole project, it's very easy to rename the folder or the variable
refs #9178
- first iteration of tidying up the unit tests
- this is useful in the current stage, because if i move files in the server folder, i need a clean folder/file structure to detect which tests needs to move
- this is a simple cleanup to reflect the current server folder structure
