Investigate Software Image Metadata for Science Platform

For the use cases:

• Science User image discovery
• Platform image launching
• Execution brokering

A number of recently completed SRCNet features have been very useful for learning about the tools and technologies available for managing software/image metadata.  This feature is to bring those features together in a cohesive plan.
