Moves the MSRV requirement to the workspace and expands it to all
cloud-hypervisor dependencies and dev-dependencies.
This improves discoverability for new contributors working on crates
other than the cloud-hypervisor itself and creates consistency regarding
the MSRV of cloud-hypervisor dependencies.
Functionally, this doesn't change anything for dependencies of the
cloud-hypervisor crate as the MSRV requirement is already enforced by CI
when building the cloud-hypervisor with the MSRV versioned compiler.

A major improvement to the developer experience of clippy in
Cloud Hypervisor.
1. Make `cargo clippy` just work with the same lints we use in CI
2. Simplify adding new lints

This streamlines the code base to follow best practices for
error handling in Rust: Each error struct implements
std::error::Error (most due via thiserror::Error derive macro)
and sets its source accordingly.
This allows future work that nicely prints the error chains,
for example.
So far, the convention is that each error prints its
sub error as part of its Display::fmt() impl.

Rust 2021 edition has a few improvements over the 2018 edition. Migrate
the project to 2021 edition by following recommended migration steps.
Luckily, the code itself doesn't require fixing.
Bump MSRV to 1.56 as it is required by the 2021 edition. Also fix the
clap build dependency to make Cloud Hypervisor build again.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.
