[WIP] 6.9 netstandard 1.3 beta1

[eByte23]

So I have done the basic implementation of the dotnet db interfaces and also lower our require dotnet ver to netstandard 1.3 :D (Winning)!

I will be implementing all the test also in dotnet core, so we can test how reliable the work is

Going to do more clean up and bring back code so that we can make it more approachable as a merge-able pr for mysql branch

As metioned #1

Shouldn't this be merging to 6.9_netstandard_1.5 rather than 6.9... or a new branch for netstandard 1.3?

Ahh crap yes
