* Add periodic callhome functionality Periodically (every 24hrs by default), fetch callhome information and upload it to SUBNET. New config keys under the `callhome` subsystem: enable - Set to `on` for enabling callhome. Default `off` frequency - Interval between callhome cycles. Default `24h` * Improvements based on review comments - Update `enableCallhome` safely - Rename pctx to ctx - Block during execution of callhome - Store parsed proxy URL in global subnet config - Store callhome URL(s) in constants - Use existing global transport - Pass auth token to subnetPostReq - Use `config.EnableOn` instead of `"on"` * Use atomic package instead of lock * Use uber atomic package * Use `Cancel` instead of `cancel` Co-authored-by: Harshavardhana <harsha@minio.io> Co-authored-by: Harshavardhana <harsha@minio.io> Co-authored-by: Aditya Manthramurthy <donatello@users.noreply.github.com>
