Changes for #379, yarn rw db introspect

[Jaikant]

This is my first PR, and I picked an issue based on the label. Hopefully no one else was looking at it!

@Jaikant thanks so much for the PR! Check out the result of those failing build steps below, looks like it might just be a couple quick syntax tweaks.

@cannikin I also included lint in the package.json of the cli package, the reason for me missing it the first time around.

Please address comment about packages/cli/package.json

Thanks!

@cannikin @thedavidprice ok. Pushed the changes. This is how the help looks (I don't like the help text taking two lines, but probably ok?)

FYI: I should have caught this earlier, but we just updated to Prisma 2.0 Beta and switched the command line use of prisma2 to prisma. I’ll make a quick update here.

Thanks again!
