-----------------------------------------------------------------
Submitted a patch which fixes one more issue where KDiag is not able to print any krb5.conf line starting with hash (#).

> If Kerberos credential cache file location is overridden in environment, then KDiag tries to read its value for Kerberos configuration. For example,
> {code:java}
> # export KRB5CCNAME=/tmp/krb5cc_1001
> # hadoop org.apache.hadoop.security.KDiag
> ...
> ...
> == Locating Kerberos configuration file ==
> Setting kerberos path from environment variable KRB5CCNAME: "/tmp/krb5cc_1001"
> Kerberos configuration file = /tmp/krb5cc_1001
> 17/12/16 04:06:19 ERROR security.KDiag: java.util.UnknownFormatConversionException: Conversion = '�'
> java.util.UnknownFormatConversionException: Conversion = '�'
> {code}
> Expected Behavior:
> 1. Kerberos configuration file location should be read from KRB5_CONFIG env. variable instead of KRB5CCNAME.
