Naming conventions altered for typescript code

[gleb-urvanov]

Applied @Lezek123 suggestion from #970

[mnaamani]

I'm trying to understand the naming-conventions rules:
Is the format array listing what is allowed or considered and error?

[Lezek123]

Those are allowed

[mnaamani]

I presume since these new rules are in #1001 it works as you want. But why did we make an exception for the types library? Can't we have a set of rules that works for the types library and the consuming apps?

The changes are introducing some linter errors in storage node:

/Users/mokhtar/joystream/joystream/storage-node/packages/util/lru.js
  87:3  error  Method name _prune must match one of the following formats: camelCase  @typescript-eslint/naming-convention

Let me add add a CI check for the storage node, and do some fixes there before we merge these new rules.
