Benchmark PR getsentry#103875

Type: Clean (correct implementation)

Original PR Title: feat(explorer): rpcs for getting log/metric attrs for a trace id + substring
Original PR Description: Adds specialized rpcs for getting a list of log/metric attribute dicts filtered by trace_id and optional substring. This is done with a single snuba rpc (not counting short id lookup) and is a lot more performant than the table queries we were doing earlier.

Return format is list of attr key-value dicts. This is different from the current tool output format which includes type, tbd if we still need to include that

GetTrace experiment:

Using https://snuba-admin.getsentry.net/#rpc-endpoints, I made requests to EndpointGetTrace and EndpointTraceItemTable for the same purpose - filter logs by a trace (2h old) in Seer project. Time range is last 30d, and I selected the same columns. The table query has an additional LIKE filter on sentry.body (message) - this isn't supported for GetTrace so we'd have to post-process in sentry or seer

EndpointGetTrace - 1318904 progressBytes (bytes processed by clickhouse)
EndpointTraceItemTable - 52792914551 progressBytes. 40k times more, prob scanning from the start of the time range. This is evidence the GetTrace endpoint is way better optimized for trace_id filters.

The requests:
