[SPARK-17783][SQL] Hide Credentials in CREATE and DESC FORMATTED/EXTENDED a PERSISTENT/TEMP Table for JDBC
### What changes were proposed in this pull request?
We should never expose the Credentials in the EXPLAIN and DESC FORMATTED/EXTENDED command. However, below commands exposed the credentials.
In the related PR: https://github.com/apache/spark/pull/10452
> URL patterns to specify credential seems to be vary between different databases.
Thus, we hide the whole `url` value if it contains the keyword `password`. We also hide the `password` property.
Before the fix, the command outputs look like:
``` SQL
CREATE TABLE tab1
USING org.apache.spark.sql.jdbc
OPTIONS (
url 'jdbc:h2:mem:testdb0;user=testUser;password=testPass',
dbtable 'TEST.PEOPLE',
user 'testUser',
password '$password')
DESC FORMATTED tab1
DESC EXTENDED tab1
```
Before the fix,
- The output of SQL statement EXPLAIN
