[SPARK-24518][CORE] Using Hadoop credential provider API to store password

## What changes were proposed in this pull request?

In our distribution,  because we don't do such fine-grained access control of config file, also configuration file is world readable shared between different components, so password may leak to different users.

Hadoop credential provider API support storing password in a secure way, in which Spark could read it in a secure way, so here propose to add support of using credential provider API to get password.

## How was this patch tested?

Adding tests and verified locally.
