Disable plugins feature (DD_INTEGRATIONS_DISABLED)

[tot-ra]

php extension can accept env var DD_INTEGRATIONS_DISABLED to disable certain (unstable?) plugins. Seems that dd-trace-js doesn't have this feature (http for example seems to always intercept requests). Would be nice to have black list of disabled plugins

Right now this can only be configured programmatically. I agree we should add an environment variable too since it would make it easier to disable plugins without any code change.

In the meantime, it would be possible to do something like this as a workaround:

// DD_INTEGRATIONS_DISABLED=express,pg

if (process.env.DD_INTEGRATIONS_DISABLED) {
  process.env.DD_INTEGRATIONS_DISABLED.split(',').forEach(name => {
    tracer.use(name, false)
  })
}

And how do I do it in typescript, if tracer wants specific type?

name as any works for me. Hopefully your linter doesn't disagree 😅
