Subject: [PATCH] makes install available for all users in docker image (#3202)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

* makes install available for all users in docker image

moves the installation path from /root/.local to a
virtualenv. this way we still get the lightweight
multistage build without excluding non-root users.

* adds changelog entry for docker-image fix

A changelog entry has been added under the Integration
subheader

* changes dockerfile to use the venv activate script

we are now using the inbuilt venv activate script, as well
as explicitly mentioning the binary location in the entrypoint
cmd.
