Varnish Otel 2.1.0 Release

This version focuses on finer logging, introducing new environment variables that will impact the internal use of varnishlog-json and varnishncsa.

Among others:

• OTEL_VARNISH_DURATION_BUCKETS and OTEL_VARNISH_SIZE_BUCKETS define bucke sizes for histograms
• OTEL_VARNISH_LOG_TOOL can be set to ncsa to reduce the log volume considerably (at the expense of missing information)
• OTEL_VARNISH_LOG_QUERY allows to filter out logs before they are processed by varnish-otel

Check out the full varnish-otel changelog for more information.
