Explore how to remove Any constraint from I and A on Caches

There was a really interesting conversation happening on the redesign PR:

Discussion opened by @nomisRev in https://github.com/47deg/kollect/pull/14/files#r253298456

We'd most likely wanna explore ways on how to remove those constraints (I: Any, A: Any) from the method type arguments. The only limitation is the state on any DataSource implementation, where both types are needed at a class declaration level (and we don't have them til methods are called).

Important bits

We can't move I and A to the class declaration level, since caches and data sources must support heterogeneous types for the cached elements.

Also note Kotlin supports inline classes so we can also use them to enforce typing over index, data source names and data source results as we've done in Fetch.

Include two separate modules for Kotlin coroutines and for Rx2 Observables

As part of this ticket, we should add the instances too

This ticket can be split into different issues

F[_] type parameter to `DataSource` and `Data` trait for identifying requests

As in this PR.

Turn `DataSourceCache` type class parametric to F

The current implementation assumes that a Cache will return its results blocking if it needs to go async to fetch them and that is not good.

Upgrade Kotlin and Arrow

• Update Kotlin to 1.2.61 to match Kotlin version used by lastest Arrow release.
• Update Arrow to 0.7.3.

Finish IOKollectMonadErrorInstance implementation

Implement the runQuery method in arrow.effects.IOKollectMonadErrorInstance

Located at: kollect/arrow/instances/effects/instances.kt

Also, as part of this ticket, we should remove the TryKollectMonadErrorInstance, because we need support for "async" operations.

Kollect brand

We will create a brand + basic microsite template

Replace Timer with Arrow implementation

Timer was recently added to Arrow (arrow-kt/arrow#1464 (comment)). It'll be available starting on 0.9.1. Once that's ready, let's replace the implementation temporarily added to Kollect with that one.
