[KYUUBI #1262] Support both KERBEROS and PLAIN authentication at the same time

[turboFei]

Why are the changes needed?

Support both KERBEROS and PLAIN authentication at the same time.

How was this patch tested?

Added UT & IT.
I make integration testing on our dev cluster with KERBEROS and CUSTOM authentication.

kyuubi.authentication	KERBEROS,CUSTOM
kyuubi.authentication.custom.class=org.apache.kyuubi.ZeusCustom

For org.apache.kyuubi.ZeusCustom, it checks whether the user equals password.

package org.apache.kyuubi

import javax.security.sasl.AuthenticationException

import org.apache.kyuubi.service.authentication.PasswdAuthenticationProvider

class ZeusCustom
  extends PasswdAuthenticationProvider with Logging {

  override def authenticate(user: String, password: String): Unit = {
    if (user == password) {
      info(s"Success log in of user: $user")
    } else {
      throw new AuthenticationException("Username or password is not valid!")
    }
  }
}

1. kerberos testing with user b_zeus
   

2. CUTOM authentication testing with user b_zeus
   

Note that: they share the same backend spark engine, because they are the same user.

#642 introduces a UserDefineAuthenticationProviderImpl, can we use it for UTs?
