Add --release option to mic command line

Add --release option to mic command line

Rsync expects output results in mic/out/<build number>. Mic creates
<build number> subdirectory only when --release option is provided.

Adding extra command line options implementeed in mic appliance. Now
it's possible to provide additional options for mic in mic/out/command
file. This trick is utilized in this change.
job_imager puts '--release <build number>' to mic/out/command and mic
inside mic appliance uses it.
