As discussed with the product team we want to enforce kebab-case file names for
all files, with the exception of files which export a single class, in which
case they should be PascalCase and reflect the class which they export.
This will help find classes faster, and should push better naming for them too.
Some files and packages have been excluded from this linting, specifically when
a library or framework depends on the naming of a file for the functionality
e.g. Ember, knex-migrator, adapter-manager
- if the API controller endpoint is a function, we early return as we
expect the function to handle the response but we still ended up
calculating the headers beforehand, only to be thrown away
- this commit moves the header fetching code down in the flow so it's
only executed when needed
- this doesn't really have a big effect for us because 99% of our
controllers follow the object pattern

- this API framework is standalone and should be pulled out into a
separate package so we can define its boundaries more clearly, and
promote better testing of smaller parts
