chassis-state-manager: Add multi-chassis support
Add multi-chassis management support, each chassis bus separates by
giving a unique chassis id.
Current code only support single chassis, and alway assume bus name is
"xyz.openbmc_project.State.Chassis".
This patch allow user to launch chassis-state-manager with a chassis id,
and chassis id is added into service bus name for identification.
Because there are many places hardcode with bus name
"xyz.openbmc_project.State.Chassis", if chassis id is 0,
chassis-state-manager will request both
"xyz.openbmc_project.State.Chassis" and
"xyz.openbmc_project.State.Chassis0" bus name to meet backwards
compatibility.
Tested on Bletchley:
root@bletchley:~# busctl tree xyz.openbmc_project.State.Chassis
`-/xyz
`-/xyz/openbmc_project
`-/xyz/openbmc_project/state
`-/xyz/openbmc_project/state/chassis0
root@bletchley:~# busctl tree xyz.openbmc_project.State.Chassis0
`-/xyz
`-/xyz/openbmc_project
`-/xyz/openbmc_project/state
`-/xyz/openbmc_project/state/chassis0
root@bletchley:~# busctl tree xyz.openbmc_project.State.Chassis1
`-/xyz
`-/xyz/openbmc_project
`-/xyz/openbmc_project/state
`-/xyz/openbmc_project/state/chassis1
