This patch adds a new API call that allows you to get the latest available
version of a package
for each system in a list.
The use case for this in spacecmd is to be able to do a 'system_installpackage
ssm <pkg>', which
currently is quite slow because it has to call
system.listLatestInstallablePackages() for each
system to see which packages are available. By implementing this API method, a
single call
can be made to the server to get the information, which can then be used to
schedule the installations.
