export/import custom preset is needed

[nfer]

What problem does this feature solve?

Once one colleague creates a project by @vue/cli with 'Manually select features' option, it will be good if the @vue/cli command has a feature to export and import this custom preset.

What does the proposed API look like?

vue preset export > preset.conf
vue preset import preset.conf

Note: For now, you can extract the preset from ~./vuerc into a json file and then load it during create:

vue create --preset ./your-preset.json name-of-new-project
