Install system locales in web image

[dahaupt]

What happened (or feature request):

I was using the method strftime('%B', mktime(0, 0, 0, 1, 1)) in PHP to format a date (here to get the month name), but unfortunately the month was not localized to German but English only, no matter if I changed the default locale in PHP with setlocale(LC_TIME, "de_DE") before.

What the method does:
strftime — Format a local time/date according to locale settings

What you expected to happen:

The method strftime should be able to use the systems locale to format any date correctly.

How to reproduce this:

Execute this snippet in any DDEV environment:

setlocale(LC_TIME, "de_DE");
$january = strftime('%B', mktime(0, 0, 0, 1, 1));
echo $january; // should print the german localized month name 'Januar' but shows 'January'

Version: Please include the output of ddev version, docker version and the project's .ddev/config.yaml.

cli     v0.17.0
web     drud/nginx-php-fpm-local:v1.2.2
db      drud/mariadb-local:v0.9.0
dba     drud/phpmyadmin:v0.2.0
router  drud/ddev-router:v0.5.0
commit  v0.17.0
domain  ddev.local

Anything else do we need to know:

The problem is based on the fact that no locales are installed in the web container except:

C
C.UTF-8
POSIX

My workaround was to use http://php.net/manual/en/class.intldateformatter.php to format the month name which works great without having any locale installed in the web container.

Please use a complexity rating of 1-5 (5 is high) for a feature request. (High complexity implies more PR planning)

Thanks for this request!

What's required to install the locales is apt-get update && apt-get install locales-all; we would need to add this in mariadb-local's list of packages.

For people who need this immediately, it can be done in any container with

docker exec -it -uroot ddev-<projectname>-web bash
apt-get update && apt-get install locales-all

This is lost on a ddev rm unfortunately.

+1 we should have and option in ddev-config to set the local. Because we need correct date settings in php.

@dahaupt @sbaghdadi I'd love it if you could test #1106, there are testing instructions there.
