Remove timeouts from synchronous Scylla API calls

[Michal-Leszczynski]

Some Scylla endpoints returns only when the operation has been finished. In case this operation is expected to take a long time, we should just hang on the connection and wait for response - not timeout and retry, because it is less efficient and creates confusing error logs. The 2 synchronous calls used with default timeout are:

• StorageServiceRepairStatus: {"L":"INFO","T":"2023-12-01T01:31:54.398Z","N":"cluster.client","M":"HTTP retry backoff","operation":"StorageServiceRepairStatus","wait":"28.607063257s","error":"after 16m0s: context deadline exceeded","_trace_id":"uqSjtDSfRoOl1WhetiLPgA"}
• StorageServiceSstablesByKeyspacePost: {"L":"INFO","T":"2023-11-30T23:03:07.117Z","N":"cluster.client","M":"HTTP retry backoff","operation":"StorageServiceSstablesByKeyspacePost","wait":"999.175032ms","error":"after 30s: context deadline exceeded","_trace_id":"uqSjtDSfRoOl1WhetiLPgA"}
