This is refactoring in the lead up to passing mutual TLS certs for helm applications. As such we expect all applications to need config files so we can remove the logic about which applications need and do not need this (ie `#config_map?`).

This reverts merge request !20679

Resolve "API endpoint that returns all members, including the inherited membership through ancestor group"

This is mainly the setup of mutations for GraphQL. Including
authorization and basic return type-structure.

Backports relevant changes made in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/5163 to CE

HTTP host and URI should not be separated by a colon. Generated URLs was looking like http://registry.examples.com:/foo. That is throwing up let's encrypt cert requests for gitlab registry.

Without this parameter, every load of a Wiki page will load all the Wiki pages
in the repository for the sidebar. This is a significant performance penalty
that can significant slow the display of all Wiki pages.

Relates to #40101

The sanitize transformers were being duplicated each time the Markdown
renderer was called, leading to expontential growth in rendering times.

The problem was that although HTML::Pipeline::SanitizationFilter.WHITELIST
is a frozen hash, the `:transformers` array can be modified. We need
to do deep copy of this to avoid adding duplicates.

Closes #49409

These changes are useful for CE as well. For example, the MR
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20720 can make
use of some of the backported methods.

This also fixes a bug with the ImageLazyLoadFilter not doing the right
thing when an existing class attribute is present.

Part of #47424

Excludes a few filters that require more work:

* lib/banzai/filter/image_lazy_load_filter_spec.rb
* lib/banzai/filter/syntax_highlight_filter_spec.rb
* lib/banzai/filter/table_of_contents_filter_spec.rb

Part of #47424

This backports a module that was in EE for Geo so that other modules
can have structured logging support.

We also try to unify the way we setup OmniAuth, and how we check
if it's enabled or not.

This method uses Gitlab::Profiler::TotalTimeFlatPrinter internally, which is the
same as RubyProf::FlatPrinter, but the min_percent option (and new max_percent
option) applies to the _total_ time, not the _self_ time. This helps us figure
out if we're calling a library inefficiently, for instance.
