Disabled native autocomplete for dropdown filter inputs

## What does this MR do?

Disables native autocomplete for the dropdown filter inputs.

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

Did we want this on all dropdown filter inputs? The issue specifies only the 'label' filter input but I think it is relevant for any filter input?

## Why was this MR needed?

No need for native autocomplete.

## What are the relevant issue numbers?

Closes #19184

Changes calendar activities to use target reference

## What does this MR do?

Uses the targets reference in the calendar activities list. Previously it was using `#` which is wrong for merge requests.

## Screenshots (if relevant)

Removed fade when filtering results

## What does this MR do?

Removes the `opacity` change when filtering results seeing as we now do `Turbolinks.visit` it isn't required.

Best way to see issue - filter issues & then go back. Will still have opacity styling.

See merge request !4932

Add fog-rackspace microgem to support backups using rackspace provider

## What does this MR do?

Adds fog-rackspace gem to Gemfile.

## Why was this MR needed?

Because fog moved the rackspace provider to separate gem.

## What are the relevant issue numbers?

#19197

See merge request !4986

Use update_columns to by_pass all the dirty code on active_record

See merge request !4985

There are currently two cops for this:

* Migration/AddIndex: checks if indexes are added concurrently
* Migration/ColumnWithDefault: checks if columns with default values are
  added in a concurrent manner

Both cops are fairly simple and make no attempt at correcting the code
as this is quite hard to do (e.g. modifications may need to be applied
in various places in the same file). They however should provide enough
to catch people ignoring the comments in generated migrations telling
them to use add_concurrent_index or add_column_with_default.

We think this is valid because we’re just storing new data that always will be valid

Reduce overhead and optimize ProjectTeam#max_member_access performance

See merge request !4973

The previous implementation would load the entire team member list and their
respective attributes. Now we only search for the user's specific
access level.

In gitlab-com/operations#42, this reduces the overall overhead of rendering
the issue from 28% to 20%.

First step of optimizing #19273
