RFE: add group info to LSB rpm repositories

[Jeff Johnson]

Created attachment 1890 [details]
initial/example groups file

the metadata describing a repository of rpm packages (for short "yum
repository" although to be accurate this is not limited to yum usage) can
define package groups. Such groups allow installs with a single command (e.g.
'yum groupinstall "LSB SDK"') in a manner that's more "natural" to common usage
than our task packages.

The attachment contains a file in the syntax that can be passed to createrepo
with the -g flag. It defines four groups (which match the four task packages)
and combine them into a "category" such as would be seen when doing an initial
installation of Fedora/RHEL. While the syntax is validated, I'm not convinced
this file does the right stuff yet, so this attachment is for archival
purposes.

The addition of a groups file should be completely transparent - the info won't
be used unless someone asks for it (yum grouplist, yum groupinstall, etc.).
