Add possiblity to disable pypi version check via setting env var

[YevheniiSemendiak]

We need to suppress version checks in different tools, which might have a lag before the release with the latest versions (such as neuromation base environment docker image, neuro-web-shell, etc.)

As an alternative - we could also utilize the auto_envvar_prefix feature from click, but I'm not sure whether we need that thing at the moment.

Please use envvar="NEURO_CLI_DISABLE_PYPI_VERSION_CHECK" instead and show_envvar=True.

It makes the env var ustodiscoverable in generated docs
