feat: upgrade to OTel 1.8.0 / 0.34.0

[seemk]

• Upgrade to latest OTel versions
• Due to changes to the require mechanism tests started being really slow, switched on --parallel for mocha.
• Removed @opentelemetry/instrumentation-aws-lambda from the bundle as there is a separate lambda instrumentation and the package is stuck on 0.32.0 version of experimental libs (@opentelemetry/instrumentation-aws-lambda is not compatible with @opentelemetry/instrumentation@^0.34.0 open-telemetry/opentelemetry-js-contrib#1285)
• @opentelemetry/api is now a peer dependency, as optional peer dependencies give no warnings.
• Add protobufjs to dependencies as it is required in profile.js
