HADOOP-19648. Cos use token credential will lose token field

[leosanqing]

Description of PR

In the org.apache.hadoop.fs.cosn.CosNativeFileSystemStore#initCOSClient method, when the client is initialized, it only passes the access key and secret key, completely ignoring the session token. This causes all subsequent operations that rely on these temporary credentials to fail.
Furthermore, this re-initialization step seems unnecessary. Instead of creating a new client with incomplete credentials, the existing credential provider (which already contains the AK, SK, and token) should be passed down directly.

This is same as #7867 there were some conflicts. so I send up a separate pull request targeting branch-3.4.

How was this patch tested?

ITests are passed on my local env.

@cnauroth hi, bro, I send a new pr to merge targeting brach-3.4. Previous conflicts are test dependencies. ITest's results are here. Could you help me to review this pr?

[cnauroth]

+1. I'll commit this shortly.

[cnauroth]

Thank you again @leosanqing . I committed this to branch-3.4.

Thank you again @leosanqing . I committed this to branch-3.4.
Hey，thank you for your merging.

I'm not sure if branch-3.3 is still being maintained, but I have tested this PR against branch-3.3 in my local environment, and it passed. If you are still releasing new versions for 3.3, this could be merged into branch-3.3 as well, since it was the original branch where this COS feature was first introduced.
