Storage module refactoring

[DmitryAstafyev]

Chipmunk needs to save some data on a disk (recent actions, filters, charts, bookmarks and etc). Requests to save/load data mostly comes from client via IPC. Implementation of storage (IO operations) done on electron level (nodejs). Current solution has a couple of weak points:

• data stored as a JSON string. In the case of a big dataset it might be a problem to exchange data with client with IPC. Currently, we are not limited here: if a dataset is 10 Mb, 10 Mb will be sent to the client completely. It has to be done in some cases (loading of application for example), but it is useless in case of pulling updates for example.
• current implementation of storage done in the scope of electron module (nodejs) and gives us unnecessary dependency to the electron as itself.

Suggestion:

• it would be nice to move a storage module to the rust side

Specification (in general it should be some kind of database):

• indexes/keys: a uuid of storage (name of table in database's terms) and uuid of record in storage
• type of record: string
• storage features: create storage; drop storage; overwrite storage
• records features: insert, remove, overwrite, read
