Subject: [PATCH] core: implement per unit journal rate limiting
Add LogRateLimitIntervalSec= and LogRateLimitBurst= options for
services. If provided, these values get passed to the journald
client context, and those values are used in the rate limiting
function in the journal over the the journald.conf values.
Part of #10230
(cherry picked from commit 90fc172e191f44979005a524521112f2bd1ff21b)
Resolves: #1719577
