Title: common: -- support for env_to_vec

When CEPH_ARGS is parsed each side of the -- must be appended to the
corresponding side of the existing argument list. For instance when

-a -b -- foo bar

is merged with a CEPH_ARGS containing

-c -d -- frob nitz

it must become

-a -b -c -d -- foo bar frob nitz
