Log LDAP lookup errors and don't swallow unrelated exceptions

- Previously all exceptions were ignored, now only `Net::LDAP::Error` and exceptions that inherit from it are caught by the `rescue` clause. There might be other exceptions that should also be ignored / dealt with.
- Not sure if the Rails production log is a good choice for this, or if the GitLab application log would be more appropriate.

Send ajax request for label update only if they are changed

## What does this MR do?

At the moment we send requests to update the labels on issue even if nothing has been changed. This fixes that and only sends requests when something has actually been changed.

The code gets the initial selected values based on the inputs & then compares that to the selected values when submitting. If they are equal, then no request is sent.

## What are the relevant issue numbers?

Closes #19472 

See merge request !5071

Fix pipelines table headers

## What does this MR do?

Removed stages loop for a single 'Stages' header.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The headers were messing the table up. Note the redundant headers and squished cells.

Fix IssuesController#show degradation including project on loaded notes

See merge request !6540

* No need to re-fetch issues from GH to read their labels, the labels
  are already there from the index request.
* No need to look up labels on the database for every application, so we
  cache them.

This should avoid having large memory growth when importing GitHub repos
with lots of resources.
