Add persistent storage grpc APIricefish_17.92.0ricefish/17.92.017.92.0

In the current demo, user settings such as radio stations and HVAC preferences are lost upon poweroff. The agl-persistent-storage-api
adds a simple grpc API that enables persistent storage of
key-value pairs using RocksDB.

The API supports Write, Read, Delete, and Search calls, as well as
calls to recursively list or delete nodes (intended for use with
VSS-like keys) and to destroy the database. Separate namespaces
are also supported.

The API is written in Rust, the repo can be viewed under this URL:

Test builds were successfully carried out by Jan-Simon Möller.

+DESCRIPTION = "A grpc API that provides persistent storage for the Automotive Grade Linux demo"
+SUMMARY = "Our goal is to develop a grpc API for AGLthat serves as persistent storage API for the demo. The API will be written in Rust and make use of tonic for grpc functionality as well as RocksDB as a database backend, using rust-rocksdb. Use cases include retaining settings over a system shutdown (e.g. audio, HVAC, profile data, Wifi settings, radio presets, metric vs imperial units)."
