I18N meta issue

[teleclimber]

Need to make internationalization and localization a thing in Dropserver.

First need to choose how to support i18n (libraries, tools).

Translations of strings:

• ds-host backend (go)
• ds-host frontend (Vue)
• ds-dev backend (go, some might be shared with ds-host)
• ds-dev frontend (Vue)

Integration of i18n user selections throughout system:

• set preferred language in ds-host and ds-dev
• make it so apps can accept a preferred language from host
• make it so each user of an appspace can select their preferred language? (maybe)
