Peter Suschlik 32081ad8db Make nginx's SSL ciphers configurable ...

http://bettercrypto.org/ suggests to restrict `ssl_ciphers`.

GitLab allows weaker SSL ciphers due to some Java IDEs.

This commit make SSL ciphers configurable via the environment variable
`SSL_CIPHERS`.

Example in docker-compose.yml:

    version: '2'
    ...
    services:
      ...
      gitlab:
        ...
        environment:
          - SSL_CIPHERS=EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA256:EECDH:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:kEDH:CAMELLIA128-SHA:AES128-SHA
