[EPIC] Storage

[Slickbird]

EPIC of #106

Storage for Rust based Impl of Rosetta SDK, Includes:

Features:

• Database
• Error Storage
• Encoder
• Modules

Description:

• All persistent data must be written to the /data directory. If the node you are working on utilizes a database (like Postgres) to store data reliably, ensure this is configured to save information to this directory (and in a manner that would not corrupt any data stored by the core node process or other necessary services). It must be possible to stop all services defined in the Dockerfile and restart them (without corruption) using only the state stored in this /data directory.
