feat: add MongoMemoryReplSet class (#81) thanks @jloveridge

* chore(flow-types): Update flow-typed definitions.

Newly provided definitions:
  * get-port
  * getos

New definition via `flow-typed install`:
  * rimraf

* chore(types): Make flow and TypeScript types a bit more specific.

* chore(editorconfig): add .editorconfig so compatible editors will honor code style by default.

* chore(vscode, flow): Prevent VSCode from complaining about flow types in `js` files.

* chore(replset): Implement MongoMemoryReplSet

* docs(replset): Add documentation on replica set usage.
