[fix][COM][hadoop-common] resolve kerberos tgt expiry issue for cached hdfs filesystem

[v-kkhuang]

What is the purpose of the change

Background/Problem:
When the HDFS FileSystem cache is enabled in a Kerberos-secured cluster, the cached FileSystem holds a Kerberos TGT that can expire over time. Once expired, reusing the cached FileSystem leads to Kerberos authentication errors, because the cache returns the stale FileSystem without checking TGT validity.

Purpose of Change:
To address this problem, this PR adds a feature switch linkis.hadoop.hdfs.tgt.proactive.check.enable (default off). When enabled, before returning a cached FileSystem the code checks the UGI's TGT validity via a new KerberosTgtUtils; if the TGT has expired, the stale cached container is removed and a new FileSystem with a fresh TGT is created.

Value/Impact:
After the change, cached HDFS FileSystems are no longer reused once their Kerberos TGT expires, eliminating authentication failures in long-running cached scenarios. The switch defaults to off, so existing behavior is unchanged when disabled.

• Add UGI field and isTgtValid() method to HDFSFileSystemContainer
• Add proactive TGT expiry check in HDFSUtils: remove stale cached FileSystem and recreate with fresh TGT when expired
• Add test assertion for the new switch default value
