[fix](memory) fix Hadoop metrics2 memory leak causing FE OOM in external table workloads

[shuke987]

What problem does this PR solve?

Each new Hadoop FileSystem instance (e.g., S3AFileSystem) registers metrics
with the global DefaultMetricsSystem singleton but never unregisters them on
close(). Since Doris disables the Hadoop FS cache, every cache miss creates a
new FileSystem, causing MetricCounterLong and MBeanAttributeInfo objects to
accumulate unboundedly until OOM.

use standby mode -Dhadoop.metrics.init.mode=STANDBY to solve this problem
