knex integration does not work with OpenTelemetry (possible OpenCensus) for node.js <14.5.0

[aabmass]

OpenTelemetry relies on node.js async hooks context in async calls. More details here:

This package provides async-hooks based context manager which is used internally by OpenTelemetry plugins to propagate specific context between function calls and async operations. It only targets NodeJS since async-hooks is only available there.

Unfortunately, this doesn't work with "thenables" which is knex.js uses (see open-telemetry/opentelemetry-js#940, knex/knex#3550) for node versions <14.5.0 (see nodejs/node#22360).

Thankfully, there is an existing plugin that solves this has solved this context issue for knex, which sqlcommenter-knex can base a solution on: https://github.com/myrotvorets/opentelemetry-plugin-knex/blob/bd5f2d918eeaa86c257f5e433772ec57b4834582/lib/knex.ts#L115

I have verified that this is working in newer node versions without any code changes.
