Simplify Service Ping download options

Problem

We currently have multiple options to manually download service ping files for self managed users which is creating confusion. The goal of this epic is to simplify service ping download options for our self managed customers. See also #423957 (comment 1558378246) for current options

Desired Outcome

• There is one method to download service ping data
• Manually downloading the data should provide the same data as automatically sending it
• Documentation has clear instruction on how to manually download data ( with/ without service ping enabled)
• CSM teams are kept informed about this change

Proposed Solution

1. Check whether the service ping "Preview" functionality on admin/application_settings/service_usage_data is in any way different to the one in /admin/application_settings/metrics_and_profiling (Usage Statistics). If that's the case bring it up with PM to figure out which option to take.
2. Add the download service ping functionality from admin/application_settings/service_usage_data to /admin/application_settings/metrics_and_profiling (Usage Statistics) next to the Preview button
3. Remove admin/application_settings/service_usage_data completely

Further Actions

1. Update any documentation around this
2. Coordinate with @tjayaramaraju to let CSMs know about the change
