Issue Number: close#25093
We can set hdfs hedged configs when creating catalog, just like this:
```
CREATE CATALOG `test_ctl` PROPERTIES (
...
"dfs.client.hedged.read.threadpool.size" = "128",
"dfs.client.hedged.read.threshold.millis" = "500",
...
);
```
It is redundant to set these configs at BE side, and it will brings an occasional bug at #25093 .
- fix when modifying comments in property, it will modify the comments in the catalog
- add `alter catalog modify comment` to modify comment for catalog
- abstract some logic of `alter catalog` to parent class
If user has database with same name mysql, will introduce problem when doing checkpoint.
Solution:
Add check for this situation, if duplicate, exit and print log info to prevent damage of metadata;
Add fe config field: mysqldb_replace_name to make things correct if user already has mysql db.

This pull request addresses the behavior of the `lower_case_table_names` parameter for jdbc catalog's based on the configuration of the internal table's corresponding parameter.
Changes:
- For internal tables, if `lower_case_table_names` is set to 1 or 2, thejdbc catalog's parameter is forcefully set to `true`.
- For internal tables, if `lower_case_table_names` is set to 0, the jdbc catalog's parameter can be either `true` or `false` with a default value of `false`.
These adjustments ensure consistency and predictability when working with both internal and external table configurations in Doris.
1. Fix data size calculation of auto sample, before this pr, the data size is include all the replicas
2. Move some auto analyze related options to global session variable
3. Add some logs
Fix 2 issues:
The replication num analysis will throw exception when there is no BE alive when FE restart.
org.apache.doris.common.AnalysisException: errCode = 2, detailMessage = errCode = 2, detailMessage = replication num should be less than the number of available backends. replication num is 1, available backend num is 0
