Bug 1264 - Multiple Usability Changes to MD-SAL App Archetype

Bug 1264 - Multiple Usability Changes to MD-SAL App Archetype

1) The "generate" bundle would lay down files which are actually automatically generated
when you compile the yang file. Since these files would be overwritten when we do a compile
we removed them from our archetype and let standard generation deal with creating them.
These files are auto-generated when you build the yang file and thus not necessary.
2) Split the initial xml into a provider and consumer initial xml files.
Used naming (05 for provider, 06 for consumer) to show priority (consumer requires provider)
3) Modified the generate to place the config subsystem xml files for producer / consumer
under their respective directories. (This way if they want to ship them, but not
auto deploy we have provided a best practice)
4) Added a file named Archetype_Next_Steps.README in the root folder which outlines
some quick next steps that people can follow in place of the wiki (it still references
wiki for more details)
5) Added comments to the .gitignore
6) Added missing provider config file template.
