import: import log crate as baseline

Import from log crate 3aa1359e926a39f841791207d6e57e00da3e68e2 at https://github.com/rust-lang/log

This is as follow up to decision in CFG Logging: eclipse-score/inc_mw_log#6 (comment)
to enable Rust code with common frontend.

Please consider that this is only enabler (eclipse-score/inc_mw_log#5), and frontend will be done from scratch in S-CORE (however it will be macro compatible). The Rust binding to C++ mw::log will be located in new logging repo.

@hoppe-and-dreams @rmaddikery @arsibo The frontend was moved as requested. (FYI: @darkwisebear )

Can you please first request the upstream to change if that doesn't work we should to a real fork in a separate repository.

Not sure what does not work ?:)

Since the repo does not have all the checks in place please add in description if you follow Rust's naming convention and coding guidelines? E.g.: https://github.com/rust-lang/style-team/blob/master/guide/guide.md

I see few unit tests, but not covered for all. Is this planned?

Follow ups plannned after this PR:
eclipse-score/score#1896
eclipse-score/score#1897

For "imported" code, this is as is. As in above, this going to be fixed in MVP

A readme can be useful that demonstrates the usage and assumptions of use

As this is enabler from open source, no UT planned for this code. Only for new MVP providing proper frontend.

[rmaddikery]

IS this missing?

[pawelrutkaq]

Done

Quality and naming output:
pawel@pawel-VirtualBox ~/qorix/repos/baselibs/score/mw/log/rust (pawelrutkaq_rust_log_frontend) $ cargo clippy

So common pratices for Rust followed.
