Test code in `lib` package requires cgo, but cgo is not allowed in `*_test.go` files, so we import a lot of testing-related code into a library which also has a lot of side-effects. This fix adds a build tag `e2e_test` as a workaround.
This PR refactors CLI API, removes obsolete commands and splits status code into smaller pieces:
* get rid of subcommands API (no ./status <command>)
* get rid of custom cli app package
* use stdlib flag package for handling command line flags
* move cross-compilation / mobile related code to lib/ package
* move wnode command into separate binary (cmd/node-status, name is subject to discuss)
* remove faucet command as obsolete
* update/add docs/READMES/wikis for new command line flags
It makes statusd code much simpler and smaller, separates concerns (lib, wnode and statusd are different things).
