- it seems that fetching the active configuration for a project
using an ICConfigurationDescription is time-consuming
- the active configuration is sought in ContainerCommandLauncherFactory
to get the optional build properties and thus we can figure out
if the active configuration has enabled container build or not
- see if we are given a CConfigurationDescriptionCache and it
contains a BuildConfigurationData element which allows us to
get an IConfiguration without creating a new one, serializing
it etc.. which is adding to the time taken
