RFR 8034762: Move krb5.conf related tests into a single place

[Wang Weijun]

Hi All

The bug is at https://bugs.openjdk.java.net/browse/JDK-8034762.

Basically there is nothing to review. I just move 10 files to a different directory and not a single bit of their contents was changed. They are

    test/sun/security/krb5/ConfPlusProp.java
    test/sun/security/krb5/ConfigWithQuotations.java
    test/sun/security/krb5/DnsFallback.java
    test/sun/security/krb5/ParseCAPaths.java
    test/sun/security/krb5/ParseConfig.java
    test/sun/security/krb5/confplusprop.conf
    test/sun/security/krb5/confplusprop2.conf
    test/sun/security/krb5/edu.mit.Kerberos
    test/sun/security/krb5/krb5-capaths.conf
    test/sun/security/krb5/krb5.conf

Thanks
Max
