pm:enable should be pm:install

[jhodgdon-drp]

Describe the bug
In Drupal 8.x and above, there is no longer a way to "enable/disable" modules. Instead we "install/uninstall" them.

However, Drush still has a pm:enable command along with pm:uninstall.

This is confusing (enable is the opposite of uninstall?) and inconsistent with the Drupal UI.

To Reproduce
List commands in Drush and you'll see that pm:enable turns a module on, and pm:uninstall turns it off (which also involves adding/removing configuration, database tables, and/or content).

Expected behavior
The pm:enable command should be named pm:install for consistency with the Drupal UI and with the pm:uninstall command.

System Configuration

+1 we can keep pm:enable as an alias, so there is little cost to doing this.

Yeah, this is a good proposal ... The docs web page will change url. We could add a redirect plugin for mkdocs if we want to avoid a few 404s.

I have create PR #5061
Also kept alias "install, pm-install, en, pm-enable, pm:enable" for pm:install
@weitzman could you please review changes in PR.

I have tested this on local and confirming that below all commands are working fine, as expected.

drush en
drush pm-enable
drush pm:enable
drush install
drush pm-install
drush pm:install

This is an improvement, but for consistency, shouldn't we also add an un alias for pm:uninstall, just as pm:install has in?

pm:install

Aliases: in, install, pm-install, en, pm-enable, pm:enable

pm:uninstall

Aliases: pmu, pm-uninstall

[gitressa]

I created a PR which adds a un alias, #5131.

$ drush | grep pm:uninstall
  pm:uninstall (un, pmu)      Uninstall one or more modules and their dependent modules.

$ drush un diff
 [success] Successfully uninstalled: diff
