Add object-reconstructor for swift EC

Swift Erasure Coding requires the object-reconstructor to be running,
this PR adds the object-reconstructor configuration and systemd/upstart
file.

Additionally, this PR adds testing for an erasure-coding policy as well
as for multiple policies in 1 deployment.
