Resolves: bug 282741

Bug Description: Show-Stopper - Migration from DS 6.21 to DS80
Reviewed by: nhosoi (Thanks!)
Fix Description: Added a new function migrateNetscapeRoot which will create a temporary LDIF file from the given NetscapeRoot.ldif file.  The function will look for all \bNetscape\b occurances and convert them to @capbrand@ where that is defined as the capitalized brand name in configure.   It will then import this temporary LDIF file and delete it.
Platforms tested: RHEL5 x86_64
Flag Day: no
Doc impact: no
QA impact: should be covered by regular nightly and manual testing
New Tests integrated into TET: none
