As discussed here, we should provide support for fetching agent configuration from APM server. Currently, only the TRANSACTION_SAMPLING_RATE configuration is provided.

Note: Implementation details are still being worked out by the team. see the above issue for more.

• Provide Docs
• Investigate using If-None-Match and etag
• Investigate the appropriate interval to fetch the config -> decided against periodic fetching of configs due to overhead.
• Provide tests
• Provide configuration to enable this feature
• This feature should be disable by default (We should make it clear that users need to enable this in the agent)
