Add the microlibrary cats-testkit-scalatest for testing with scalatest, containing StrictCatsEquality.

I can grab this really quickly if no objections are taken to my template. Example in discipline-specs2 and discipline-scalatest.

Maybe it makes sense to combine it with https://github.com/IronCoreLabs/cats-scalatest unfortunately it does not seems well maintained

We can do that later. Right now we need this for 2.0 release

cats-testkit-scalatest 1.0.0-M1 Released! https://github.com/typelevel/cats-testkit-scalatest

The only library I can find for Cats 2 providing CatsSuite is cats-testkit-scalatest. But this depends on bleeding edge ScalaTest libraries that contain significant breaking changes (e.g. GeneratorDrivenPropertyChecks no longer works with Gen instances from ScalaCheck). Is this the intention? It'd be great to be able to upgrade to Cats 2 without needing to worry about lots of tests breaking and needing to be rewritten.

@rajit-iov42 There's currently an RC-quality version out. IMHO that should be sufficient for tests.
