wp plugin get: remove unreliable 'update' field

we'd have to call wp_update_plugins() on each run, like we do for `wp
plugin status`

also, `wp theme get` doesn't have it
Update `wp user-meta` to support `user_login` as a first positional argument
Update tests to reflect 7433cdb
`post_type` is a special key that should also support multiple arguments
Add another example to the description
Copy and paste some command docs
Update `wp post list` examples
Merge pull request #970 from wp-cli/support-user-login-970

Support `user_login` as first arg for `wp user-meta`
According to core, `post_type` == `any` has to be a string
Merge pull request #971 from wp-cli/multiple-post-type

`post_type` should also support multiple arguments
rename _list() to list_() to avoid confusing it with a non-public method
more renaming from _list() to list_()
