Resolve "Destroying a project causes post_decline_request to be executed"
## What does this MR do?
Ensure we don't send "access request declined" to access requesters when a project is deleted.
## Are there points in the code the reviewer needs to double check?
I've created a service to decouple the notification sending from the AR model.
## Why was this MR needed?
Because there was an issue.
## What are the relevant issue numbers?
Fixes#18755, #18750.

Move pre_process into render_result
This MR moves `Banzai::Renderer.pre_process` into `Banzai::Renderer.render_result`.
The `pre_process` method was called even when its output would be ignored. See 11a5a4f359ee57029dbfcc9185fc6b47243ea2aa for more details.
See merge request !4830
In the past this class would use Project#get_issue to retrieve an issue
by its ID. This method would automatically determine whether to return
an Issue or ExternalIssue.
This commit changes IssueReferenceFilter to handle external issues again
and in a somewhat more explicit manner than before.
Fixesgitlab-org/gitlab-ce#18827
The method Banzai::Renderer.pre_process would always be called,
regardless of whether the Markdown to render was already cached or not.
In cache the document _was_ cached the output of the pre-processing
pipeline was ignored resulting in it doing nothing but wasting CPU
cycles.
This commit moves Banzai::Renderer.pre_process into
Banzai::Renderer.render_result so that it's _only_ used when needed.
A lot of git operations were being repeated, for example, to build a url
you would ask if the path was a Tree, which would call a recursive routine
in Gitlab::Git::Tree#where, then ask if the path was a Blob, which would
call a recursive routine at Gitlab::Git::Blob#find, making reference to
the same git objects several times. Now we call Rugged::Tree#path, which
allows us to determine the type of the path in one pass.
Some other minor improvement added, like saving commonly used references
instead of calculating them each time.
Show proper image ID on registry page
## What does this MR do?
Display the container registry image ID (from the config blob) instead of the first image layer ID
## Are there points in the code the reviewer needs to double check?
## Why was this MR needed?
To show proper image ID on container_registry page.
This only supports manifest V2, since the manifest V1 doesn't expose information about Image ID.
## What are the relevant issue numbers?
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/18159.

This commit builds on the groundwork in
ee008e300b1ec0abcc90e6a30816ec0754cea0dd, which refactored the backend
so the same code could be used for new dropdowns. In this commit its
used for templates for the `.gitlab-ci.yml` files.

Fix RangeError exceptions when referring to issues or merge requests outside of max database values
When using #XYZ in Markdown text, if XYZ exceeds the maximum value of a signed 32-bit integer, we get an exception when the Markdown render attempts to run `where(iids: XYZ)`. Introduce a method that will throw out out-of-bounds values.

1. An exception would be raised if the filter was called with an invalid
URI. Mainly because we weren't catching the `Addressable` exception.
2. This commit fixes it and adds a spec for the filter.
Track method call times/counts as a single metric
This changes method call tracking so only a single metric is emitted regardless of the number of calls. This allows us to more accurately measure the total execution time of a method as well as the number of times a method is called. See 851e3ff7578973c2206628424eac3b951a3c656d for more details.
Method call tracking tracked calls individually meaning the end statistics may not always be accurate enough to get a good understanding of where time is spent.

Previously we'd create a separate Metric instance for every method call
that would exceed the method call threshold. This is problematic because
it doesn't provide us with information to accurately get the _total_
execution time of a particular method. For example, if the method
"Foo#bar" was called 4 times with a runtime of ~10 milliseconds we'd end
up with 4 different Metric instances. If we were to then get the
average/95th percentile/etc of the timings this would be roughly 10
milliseconds. However, the _actual_ total time spent in this method
would be around 40 milliseconds.
To solve this problem we now create a single Metric instance per method.
This Metric instance contains the _total_ real/CPU time and the call
count for every instrumented method.
