chore(dynamic-sampling): quiet redis noise in schedule_project_config

[shellmayr]

• A dependency to the util was added before I merged without rebasing on master, which broke imports in chore(dynamic-sampling): quiet redis noise in schedule_invalidate_project_config #101331
• Use the context manager introduced in fix(aci): Quiet Redis exception noise #99955 to quiet redis noise in dynamic sampling
• Move the context manager and related utils to a central point, since this will be useful across the repo

Closes TET-1227

TET-1227 Dynamic Sampling: Cache Timeouts

[kcons]

FYI, this doesn't actually help with RedisClusterException grouping unless you report within the context.
This is a nuanced violation of expectations, so I put up #101547 to address it.
