[PR] [fs] Align OSS User-Agent with Jindo [paimon]
sundapeng opened a new pull request, #10306:
URL: https://github.com/apache/paimon/pull/10306
### Purpose
OSS requests from `paimon-oss` carry only the SDK's default User-Agent, `aliyun-sdk-java/3.17.4(Linux/...;<java>), Hadoop/3.3.4`, so Paimon traffic can't be told apart from other SDK traffic in OSS access logs. The DLF access tracking info (`dlf.access-tracking.extended-info`) that `JindoFileIO` appends to the User-Agent is also dropped on this path.
`OSSFileIO` now builds `fs.oss.user.agent.prefix` in the layout Jindo uses, `module(transport;features) extended`, from the same `fs.oss.user.agent.module/features/extended` keys:
- The module defaults to `Paimon/<version>` and the transport is `aliyun-sdk-java/<version>`.
- The access tracking info is appended after any user-set extended value.
- A user-set `fs.oss.user.agent.prefix` still takes precedence.
For example: `Paimon/2.2-SNAPSHOT(aliyun-sdk-java/3.17.4;Flink) vvr uid/123, Hadoop/3.3.4`.
### Tests
`OSSUserAgentTest`: 6 new cases, 1 of them against a fake OSS endpoint; 30 tests in `paimon-oss-impl` passed.
