client: parse env variables before sending job-file contents to server
Fixes "fio environment var bug".
https://www.spinics.net/lists/fio/msg07093.html
Add read_ini_data() to parse and expand env variables within job-file
before sending to server. By doing this, clients can control parameters
embedded within the job-file, without server side having to set them
separately.
