Ticket 48983 - generate install path info from autotools scripts

Bug Description:  At configure time, this is the only time we know all the
resolved paths of a ds installation. However, external tools such as lib389
need to be able to discover and use these paths.

Fix Description:  Add a new file to share in a well-known location that well
provide all the paths of ds instance and install. This will allow discovery
of what settings should be used on the associated platform or installation.
