fix: Updated instrumentation registration to allow for instrumenting of a local file that does not exist within node_modules. You must pass in absolutePath with the absolute path to the file that is being instrumented along with the moduleName which in this case is just the file name without the extension

[bizob2828]

Description

We tried to add instrumentation for local files. This was done in [messaging-app] but was using v9.x of the agent. In v11.0.0 we now use require-in-the-middle for instrumenting CJS, which requires additional work to instrument files that are not within a 3rd party module. This PR fixes that by providing a new absolutePath key:

'use strict'

const newrelic = require('newrelic')
const niftyPath = require.resolve('./nifty-messages')

newrelic.instrumentMessages({ absolutePath: niftyPath, moduleName: 'nifty-messages', onRequireHandler)

How to Test

node test/integration/module-loading/module-loading.tap.js adds a new test for this.
