* Pull in entire unit-rust-sdk project
  * not included: CLA, COC, License
  * not included: duplicate openapi spec
  * not included: CI workflows
  * not included: changelog tooling
  * not included: commitsar tooling
  * not included: OpenAPI Web UI feature
* update links in unitctl manpage
* remove IDE configuration from .gitignore
* rename Containerfile.debian to Dockerfile
* simplify call to uname
* keep Readmes and Makefiles to 80 character lines
* outline specifically how to build unitctl
  for any desired target, and where to then
  find the binary for use
* remove a section on the vision of the CLI
  which was superfluous given the state of
  completeness of the code and its use in
  unit
* remove out of date feature proposals from readme
* makefile: do not run when Rustup is not present
* bump mio version to latest
* generate openapi client library on demand
  * generate-openapi only runs when not present
  * generate-openapi now a dependency of binary build targets
  * deleted autogenerated code
  * reverted readme and Cargo document to autogenerated state
  * add additional build requirement to Readme
