Jolocom DevOps CI test

Description

Create CI, which will run unit tests, build with release configuration, collect platform specific binary libraries and publish them as release artefact.

Detailed steps

• fork this repository;
• this repository is Rust's workspace - should be built like one;
• each step should continue only if previous one succeeded;
• use SHELL script for post-build binaries collection step;
• can use cargo based snippet (may require editing), but be careful with double outputs:

cargo b -q --message-format json | jq -r '
    select (
         .reason == "compiler-artifact"
     ) | select(
         .target.kind | any(
             . == "cdylib"
         )
     ) | .filenames |
     unique | .[]
'

• completing this task in any other way, but with desired result is acceptable;

Extra points (not mandatory)

• add formatter check as first step;
• CI badge[s] in the README;
• auto publish to crates.io;
• CI for different targets [Windows/Linux/MacOS/etc.];
