Replace all AWS SDK calls with their WithContext analogs

What type of PR is this?
/kind support

What this PR does / why we need it:
This is the first PR in a series.

Now we don't pass context from Reconcile functions to AWS SDK calls, which limits our ability to trace requests using OpenTelemetry. To improve this we want to start passing context from top to bottom.

In this PR we just replace AWS SDK calls with their WithContext analogs, so that they can accept a context parameter. In the following PRs we are going to start passing context from Reconcile to the SDK calls.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Partially-Fixes #4504

We are not passing the context top down still. all the contexts are TODO, so it still not serve the purpose that is stated in the PR

[Fedosin]

@Ankitasw yeah, you are right, the description is a bit confusing. I updated it to make it more explicit that in this PR we just replace SDK calls, and all work about passing contexts will be done in the following PRs.

[nrb]

Given that this is the first step in a series of work, replacing the calls with their context-aware equivalents and context.TODO() seems reasonable to me. Skimming the changes, this PR appears to be fairly low risk, though I did not dig into the test changes yet.

@Fedosin if this is going to be a series of work, can we have a consolidated issue created with the task list?

[Fedosin]

Thanks folks! I created an issue for this work: #4504

[Ankitasw]

Thanks @Fedosin , if you have a plan of work, could you mention all the work items in above issue?

[nrb]

Not an official reviewer, but I did another pass focusing on the tests, and this appears to pretty much be straight replacements like I mentioned before.

There are some functions that are expanded to receive requestOptions, but again this PR looks pretty low risk.

LGTM aside from some tracking requests on the issue.
