Use of '|' for passwords in src/docker/start.sh

[djuarezgf]

Describe your problem.

Currently, we can find the following code in src/docker/start.sh:

sed -i "s|{http-proxy-password}|${HTTP_PROXY_PASSWORD:-}|" "$file"

In this case, if the password contains the character '|', the command would have problems with it. Please look for an alternative.
