### Description of PR
The current log format of printStatistics() is:
```
2024-04-27 21:15:05,429 [main] INFO namenode.FSEditLog (FSEditLog.java:printStatistics(801)) - Number of transactions: 2 Total time for transactions(ms): 2 Number of transactions batched in Syncs: 0 Number of syncs: 3 SyncTimes(ms): 1 0
```
There are no separators between different keys, making it difficult to read. The modified format is：
```
2024-04-27 21:15:05,429 [main] INFO namenode.FSEditLog (FSEditLog.java:printStatistics(801)) - Number of transactions: 2, Total time for transactions(ms): 2, Number of transactions batched in Syncs: 0, Number of syncs: 3, SyncTimes(ms): 1 0
```
### How was this patch tested?
This patch only updates the log format and does not need to add new test cases.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
