feat: add WithContext() admin client methods

[thomas-bousquet]

Motivation

The admin client does not carry / accept the context context.Context. Accepting a context as a first parameter is a Go idiom, and can be useful when the caller wants to set a request timeout instead of tracking manually a timeout with separate goroutine.

Modifications

In order to accept that context and make this a non-breaking change, a WithContext() method equivalent is added to each of the methods in the admin client. Existing methods are now calling internally the WithContext() method, with a context.Background() for the required context.

Verifying this change

This change can be verified with existing E2E tests on the admin client for regression.
