[HBASE-16231] Integration tests should support client keytab login for secure clusters

• Type: Improvement
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 1.3.0, 2.0.0
• Component/s: integration tests

Release Note

Prior to this change, the integration test clients (IntegrationTest*) relied on the Kerberos credential cache for authentication against secured clusters. This could lead to the tests failing due to authentication failures when the tickets in the credential cache expired. With this change, the integration test clients will make use of the configuration properties for "hbase.client.keytab.file" and "hbase.client.kerberos.principal" (They are required). This will perform a login from the configured keytab file and automatically refresh the credentials in the background for the process lifetime.

Description

Integration tests currently rely on an external kerberos login for secure clusters. Elsewhere we use AuthUtil to login and refresh the credentials in a background thread. We should do the same here.
