Is your feature request related to a problem? Please describe.

MongoDB Atlas receiver doesn't appear to respect the proxy environment variables https://opentelemetry.io/docs/collector/configuration/#proxy-support, https://pkg.go.dev/go.mongodb.org/atlas/mongodbatlas.

Describe the solution you'd like

It would be ideal if the receiver supported proxy environment to that network controls could be easily implemented.

Describe alternatives you've considered

Moving the exporter to a network that allows access to the MongoDB Atlas API.
