feat(logger): refresh sample rate calculation before each invocation

[am29d]

…in logger context## Summary

Changes

Please provide a summary of what's being changed

This PR modifies the sampleRate behaviour for the logger and will now sample per invocation, instead of execution environment. When using injectLambdaContext either as decorator or as middleware, we now automatically refresh sample rate.

As discussed in #3278 we avoid duplicate sample decision during cold starts, as it might happen in the Logger constructor. To make this possible, I have exposed coldStart field from the Utility class.

Please add the issue number below, if no issue is present the PR might get blocked and not be reviewed

Issue number: closes #3278

Left one comment about a docstring, other than that I have built and tested the package and it works, same for e2e tests which are green.
