RFR 8175120: Remove old tests on kdc timeout policy

[Weijun Wang]

The new kdc timeout policy test KdcPolicy.java [1] has been running for 
some time and it's both faster and more reliable. I request removing the 
old ones:

files:
-       test/sun/security/krb5/auto/BadKdc.java
-       test/sun/security/krb5/auto/BadKdc1.java
-       test/sun/security/krb5/auto/BadKdc2.java
-       test/sun/security/krb5/auto/BadKdc3.java
-       test/sun/security/krb5/auto/BadKdc4.java
-       test/sun/security/krb5/auto/CommMatcher.java
-       test/sun/security/krb5/auto/MaxRetries.java
-       test/sun/security/krb5/auto/TcpTimeout.java
-       test/sun/security/krb5/auto/UdpTcp.java

Thanks
Max
