[RFR] 8175120: Remove old tests on kdc timeout policy

[Andrew John Hughes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8175120
Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8175120/webrev.01/
Original review:
https://mail.openjdk.java.net/pipermail/security-dev/2017-February/015625.html

This is not a clean backport because the tests in 8u differ slightly
from those in OpenJDK 10:

1. 8u has "JDK-8190690: Impact on krb5 test cases in the 8u nightly".
That same change (adding a property to the @run line) also needs to be
applied to the new KdcPolicy.java test for it to succeed.

2. 10u contains "JDK-8006690: sun/security/krb5/auto/BadKdc* tests fails
intermittently" which I assume is obsoleted by the more reliable
KdcPolicy.java test

Strangely enough, this & JDK-8164656 were already approved last July,
but never pushed [0].  I can't see how this was a straightforward
backport then though either.
