Sample for storages

[kirillt]

We need some sample binary be compiled on each commit (GitHub Actions prefixes could be used to compile only when fs-storage crate is actually modified). The sample could be very simple CLI utility working in 2 modes:

• write-only mode
  • accepts parameters:
    • path to the storage
  • verifies that the storage doesn't exist
  • interactively takes as input:
    • storage type
    • one or many KV pairs
  • writes all KV pairs by the path
• read-only mode
  • accepts parameters:
    • path to the storage
    • single key
  • outputs value from the storage on screen
