Add ability to provide a dependency file for installing plugins

[Buzut]

The cli allows to output all installed plugins in different formats: wp plugin list --format=yaml
It would be really interesting to be able to provide such a file as a parameter to install the plugins to another WordPress install.

wp plugin install --list=plugins.yml

# Maybe add a version parameter [strict | minor | major | latest]
wp plugin install --list=plugins.yml --version=strict

Thanks for the suggestion, @Buzut !
