XRay Remote Sampler - Cap quotaBalance to 1x quota

[jj22ee]

Tracking issue: #3651

Issue:

• When XRay Sampling quota is run out, quotaBalance is refreshed.
• When quotaBalance is refreshed, it is increased by: (seconds since last refresh) * quota
  • If quotaBalance is refreshed 5 seconds after previous refresh, then quotaBalance gains 5*quota. This is not desirable as it can allow for an unexpected increase burst of sampled requests after longer time periods between requests.

FIx:
Cap rule quotaBalance to 1x quota.

@Aneurysm9 Can this be merged?

This requires at least one more approval from @open-telemetry/go-approvers before it can be merged.

@Aneurysm9

Does this require go-approvers to be in the Reviewers list? Can this be done or how can we ping another go-approver to look at this PR?
