Conductr-cli

1. Small UX improvements for `load-license` - trim input, use readline, create dirs if not present, add `-v` flag
3. Now automatically adds network address aliases instead of requiring the user to type them in
4. Improved license messages

**Support licensing information as part of ConductR 2.1**
* Implement `conduct load-license` command 335, 345, 337, 341
* Modify `conduct info` to display license information where applicable 336

**Preparation work to support OCI image format**
* Modify `shazar` to support various other formats 343, 342
* Modify `conduct load` to support `stdin` input 333

**Miscellaneous features/fixes**
* Add support for inspecting bundle via `conduct info` 354
* Improve handling of ConductR startup errors 357
* Create alias `conduct start` for `conduct run` 356
* `conduct info` now displays compatibility version and roles; system, system version and endpoint name removed from `conduct acls` 352
* Prepare exposure of HAProxy stats port through sandbox 350 and 353
* Fix `conduct stop` returning non-zero code if Docker is not present 348
* `sandbox run` now validates the version number input argument 339

Includes 331 to address 330.

- Fixes a bug in network alias creation instructions on Linux -- aliases are to be created with subnet mask `255.255.255.255`.
- Fixes a bug with Java version detection.
- Adds `--no-default-features` flag to `sandbox run` to start the sandbox without starting proxying or logging
