Deleted real server string patch

[Dung Nguyen]

Real servers are "Deleted" due to two reasons:  1) due reload of the
configuration file after an update and 2) due to fail status check.

For organization that monitors the log files for actual node/resource
failure the second deletion reason is the only one they want to see.

Thus to distinguish between the two I am submitting the following patch.  It
retains the string "Deleted real server" for the first reason.

And for the second reason, the string is modidifed to "Purged real server".

For organization that monitors the ldirectord log files, they can watch for
the string "Purged real server" and take appropriate action.

Note:  The patch I am submitting is for version 1.120, the official version
that my organization is using.  It can easily be extracted and applied to
the latest version.
