unable to use container with extravars

It is impossible to run playbook with extra-vars in format '{a: true, b:["c","d"]}' reason for this is using of parameters="$@" which cause parameters to be taken from splititng on space.

Solution to this would be using "$@" directrly on gosu command.

Background: Lets assume command was run with parameters --extra-vars '{a: true, b:["c","d"]}'

• "$@" - in bash is equivalent to "$1" "$2"which result in--extra-vars '{a: true, b:["c","d"]}'`
• "$parameters" - results in --extra-vars '{a:' true, b: '["c",' '"d"]}'` since variable is splited on space.
