Simplify stage extrapolation

Small GraphQL improvements

* Use connection_type for an array of objects
* Update GraphQL description for job need name

Remove include_merged_yaml parameter

Removes the include_merged_yaml parameter to make code more idiomatic.
The parameter isn't stored, it's computed dynamically when accessed so
this introduces a slight performance overhead, but it's far outweighed
by the pro of having cleaner code and less technical debt.

Stub YamlProcessor response in resolver specs

Refactor relation connection types

* Move request type tests to request specs
* Use proper status enum values

Simplify Ci::Config GraphQL resolver

Refactors to use string as content type

* Refactors mutation to use STRING_TYPE rather than ApolloUpload, since
the mutation cannot work with a path from the frontend
* Removes YamlProcessorResult type and returns StageType instead
* Adds status field to mutation to mirror implementation
* Makes comprehensive specs

Adds a changelog

Filters out jobless stages

Refactored to use custom types

* Added a ci_config type for stages, groups, jobs, needs
* Adds a new gitlab-ci.yml stub that has some includes
* Updates specs
* Updates docs and schema

Updates mutation to be a resolver instead

* Due to some changes, this was better fitted to be resolved in its own
resolver instead of being a mutation. Specs were changed and slightly
modified to reflect this.
* Adds type specs
* Adds some missing fields (size)
* Updates docs and schema
* Updates the changelog

Fixing small typo

See merge request gitlab-org/gitlab!48948

We are going to introduce new models for group wikis
than can reuse part of the existing code. This commits,
refactor those classes.

There a time window between the moment where we start the
snippet creation commit and when the git hooks are called.

In those git hooks we check that the user can only create
the default branch in the repository. Nevertheless, in that
window time, the default branch might change, resulting
in an invalid git operation.
