[improvement](jdbc catalog) Optimize connection pool caching logic

[zy-kkk]

Proposed changes

Issue Number: close #xxx

In the old caching logic, we only used jdbcurl, user, and password as cache keys. This may cause the old link to be still used when replacing the jar package, so we should concatenate all the parameters required for the connection pool as the key.

Further comments

If this is a relatively large or complex change, kick off the discussion at dev@doris.apache.org by explaining why you chose the solution you did and what alternatives you considered, etc...
