URL: https://github.com/apache/incubator-uniffle/pull/1470
### What changes were proposed in this pull request?
introduce the JvmPauseMonitor to detect the gc pause
### Why are the changes needed?
Fix: #1466
We have some loop check logic in shuffle-server, sometimes the GC pause will
make some pre-allocated buffer removed.
If we have this monitor, we will find out this reason rather than guess.
Although the JVM metrics are also valid.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Existing tests
