[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
