- Improve validations of time ranges
- Use deconstructing for named parameters in functions
- Improve time range examples in jsdoc
- Switch to placing the functions in `const`

There are basically 2 big updates in this commit:

1) Split up each range type handler into a separate function
    (plus a few helper functions).
2) Export a type infer-er

The type infer-er is useful internally, but also helps me
feel more confident about code changes. In theory no 
type should ever collide with another type, so this 
function is kind of like the "canary in the coal mine" 
in that we should always be able to test a 1:1 range 
type from this function. If we can test the types 
thoroughly, we can be more confident each respective 
handler is working on the right set of data.

On that note, splitting up the logic for each range type 
makes me feel much more confident that each one is 
handled in a way that doesn't conflict with any other. 
More importantly, any potential changes to an existing 
range type or additions of new range types will: 
A) Not cause any changes to the existing ones and
B) Scale gracefully

On that final note of graceful scaling, I find the (very
common) method of basically extending a long 
if/else if/else block to be frightening from the 
perspective of ever needing to add things. I've found 
the method I use here (a dictionary lookup, in a bunch 
of cases) to be much easier to reason about: every 
addition adds a single dictionary entry, and the JS 
selects it (O(1)) when it's needed.

The date ranges can be used to represent periods of time
relative to arbitrary points in time, such as a fixed date or the
current moment.

When credentials are changed, the field isn't marked as dirty
which results in the model not being saved or updated.

The query was passing a string for file_type when it is an int.
This is actually an unused column but was working in Rails 5
because it was just coerced to 0 which is the default value.

In Rails 6, it is now nil so no records match our query

In Rails 6, after_commit callbacks are no longer called
unless the model was saved

The behavior of this is going to change in Rails 6.1
where.not(a: 1, b: 2) is going to be:

WHERE (a != 1 OR b !=2 ) instead of WHERE (a != 1 AND b != 2)

Previously, having the `where` turned this into a relation
so `ActiveRecord::Relation#delete_all` is called.

In Rails 6, `ActiveRecord::Associations::CollectionProxy#delete_all`
is called causing an error in the query.

* Disable locking at the class-level for `update_all`

* Fixes DEPRECATION WARNING: `ActiveRecord::Result#to_hash` has been
  renamed to `to_a`. `to_hash` is deprecated and will be removed in
  Rails 6.1.

* Fix lookup of CE views

  `view_paths=` was removed so we just create a new LookupContext
  here instead of duplicating then modifying the paths

* Fix some view related spec failures

* Fix database configuration for connection pools

  ActiveRecord::Base.configurations now returns a
  ActiveRecord::DatabaseConfigurations object

We use `present_members` here so that associations are preloaded.
We do this even if there's only one record here because it raises
an exception when user.status isn't preloaded.

In Rails 6, content_type now returns the complete header. We use
media_type to just get the MIME type portion

See https://github.com/rails/rails/pull/36034

Removes patches that are already in Rails 6:
Gitlab::ContentDisposition patch
ActiveRecord::QueryCache patch
ActiveJob::Arguments patch
Gitlab::ActionViewOutput patch

Updates Activerecord::Locking::Optimistic patch to follow changes in
https://github.com/rails/rails/blob/v6.0.1/activerecord/lib/active_record/locking/optimistic.rb

Fix missing timezone for datetime_with_timezone by adding this custom
type to ActiveRecord's time_zone_aware_attributes

There are also minor changes to keep the Rails generated files
similar to when generating a new Rails 6 application

grape_logging was upgraded to fix deprecation messages related to
ActionDispatch::Http::ParameterFilter

Rails 6 now adds the nonce to style-src by default. We disable
this because we still have a lot of code that set inline styles
and we need 'unsafe-inline'
