Add locales to web container, fixes #822

[rfay]

The Problem/Issue/Bug:

in #822 a couple of users have requested locales be installed in the web container. It's easy enough to add that package locales-all

How this PR Solves The Problem:

Add locales-all

Manual Testing Instructions:

• Edit .ddev/config.yaml to use webimage: drud/ddev-webserver:20180913_locales
• Add the LANG environment variable with a docker-compose.env.yaml as shown below (example, uses de_DE.iso88591)
• ddev start
• ddev ssh to visit the web container

Example .ddev/docker-compose.env.yaml:

version: '3.6'

services:
  web:
    environment:
      - LANG=de_DE.iso88591
`

I wish it didn't, but this does add 28MB to that container, a pretty big hit for a fairly small gain. I wonder if there are smaller solutions.

I can confirm that this change works. I tested on mac osx 10.12.04 with ddev 1.1.1 . See Screenshot attached.

I also want to add, that this not set a correct date in the ddev container.

If you want to have the correct date and time you also have to add the TZ in environments. Example:

version: '3.6'

services:
  web:
    environment:
      - LANG=de_DE.iso88591
      - TZ=Europe/Berlin

Works on MacOSx 10.12.04 and ddev 1.1.1

Thanks for the testing! Getting TZ is documented in https://stackoverflow.com/questions/50255466/how-can-i-set-the-timezone-in-my-ddev-containers - I wish I'd come up with an easier way, maybe will revisit. Don't think it's much related to this though.

The thing that makes TZ hard is it's not easily accessible on macOS. Explored in #709
