fix(providers/kubernetes): Added QPS and Burst tweaks for client-side throttling

[avysochin256]

Hello

The reasoning behind this PR is to enable the adjustment of QPS and Burst configuration parameters in the client-go library.

This will help avoid constant throttling issues when dealing with over 100 K8S deployments. The default values are insufficient for such a large number of deployments.

How client-side throttling works:
// NewTokenBucketRateLimiter creates a rate limiter which implements a token bucket approach.
// The rate limiter allows bursts of up to 'burst' to exceed the QPS, while still maintaining a
// smoothed qps rate of 'qps'.
// The bucket is initially filled with 'burst' tokens, and refills at a rate of 'qps'.
// The maximum number of tokens in the bucket is capped at 'burst'.

Awesome! @valexz
I will change the target branch to beta

This is something I wanted to do for a long time and is a known issue (at least by me)

It is my first experience with public PR, and seems i did something wrong, when tried to make diff clearer for beta branch. Should I return all to the starting point, or i may just create a new PR based on beta branch?
