obmcutil: Rewrite in sh and move to phosphor-state-manager

Due to space, security, and performance concerns obmcutil is
being converted to shell script. Have implemented the basic
state interface queries (bmc, chassis, and host).

Moved to phosphor-state-manager repo as this tool mostly deals
with setting and querying state interfaces.
