* :white_check_mark: add test tasks for gRPC 1.30.0

* :recycle: move GrpcSemanticAttributes to common library for access across grpc instrumentation modules

* :sparkles: add instrumentation for grpc-shaded-netty-1.9

* :art: format grpc-1.6 build

* :bug: fix classpath for versioned test source set

* :white_check_mark: add muzzle check for module

* :art: format shaded netty module

* :recycle: move usages of grpc-common to util class

* :bug: add names to instrumentation module

* :art: format utils

* :truck: rename NettyUtils

* :truck: move around classes

* :truck: move instrumentation classes to separate file

* :bug: copy-paste build script bug

* :fire: remove unneeded helper class method

Subject: [PATCH 08/78] Upgrade otel 1 5 3 (#346)

* :arrow_up: upgrade otel

* :bug: fix buildSrc for instantiation of muzzle

* :bug: fix muzzle codegen class name

* :bug: add missing netty dependencies

* :heavy_plus_sign: add missing vertx dependency

* :poop: :construction: WIP, try to make MuzzleGradlePluginUtil available

* :bug: use instrumentation CL for muzzle

* :recycle: remove constrants as they are not needed in 0.7.0

* :heavy_plus_sign: add muzzle-check gradle plugin to tooling project

* :arrow_up: upgrade otel instrumentation version

* :recycle: depend on gradle-plugins rather than muzzle-check plugin

* :recycle: enhance mock filter to block when block=true

* :white_check_mark: add request for blocking servlet request bodies'

* :construction: add exception for blocking request'

* :sparkles: suppress HT evaluation exception for servlets

* :sparkles: block request based on filter response when reading from servlet request bodies

* :bug: fix bad null check resulting in NPE being thrown and polluting logs/hurting performance

* :sparkles: remove suppression for body reading instrumentation

* :bug: remove log statement that causes module to not load in production

* :recycle: modify Filter API to accept headers for evaluateRequestBody

* :construction: provide headers to ByteBufferSpanPair via ServletRequestInstrumentation

* :sparkles: include headers in SpanAndObjectPair

* :sparkles: rovide headers to ByteBufferSpanPair from SpanAndObject pair

* :sparkles: support body evaluation for char buffers

* :heavy_plus_sign: add bootstrap api to compile classpath

* :construction: functional custom exception handler

* :recycle: avoid exception handler approach, instead use try-catch in each onMethodExit

* :white_check_mark: add unit test reproducing issue where metric reporting endpoint would only default to trace reporting endpoint if trace reporting endpoint was supplied via env var

* :bug: fix bug with metric reporting endpoint not falling back to reporting endpoint when supplied via YAML

* :white_check_mark: add test test for non default metrics reporting endpoint

* Revert ":bug: fix bug with metric reporting endpoint not falling back to reporting endpoint when supplied via YAML"

This reverts commit 2c701073682e3e8fd8d3d665d8ea8a371684f7f8.

* :bug: fix bug more simply

* :bulb: fix comments in tests
