Add dbus interface for sol commands

Add dbus interface for sol config parameters so that after move set/get
sol config parameter command from net-ipmid to host-ipmid, the command
can send config parameters to net-ipmid sol service through the dbus
interface.

Tested by:
busctl introspect xyz.openbmc_project.Settings /xyz/openbmc_project
/network/host0/sol can show correct dbus properties of sol parameters.
ipmitool -I lanplus -H x -U x -P x raw 0x0c 0x21 0x0e 0x00 0x01
ipmitool -I lanplus -H x -U x -P x raw 0x0c 0x21 0x0e 0x01 0x00
ipmitool -I lanplus -H x -U x -P x raw 0x0c 0x21 0x0e 0x02 0x83
ipmitool -I lanplus -H x -U x -P x raw 0x0c 0x21 0x0e 0x03 0x5 0x03
ipmitool -I lanplus -H x -U x -P x raw 0x0c 0x21 0x0e 0x04 0x5 0x03
all these commands can change the dbus properties as the value in
above commands.
Before and after run these commands, ipmitool -I lanplus -H x -U x
-P x sol activate can start sol session correctly.
After reboot BMC, "Progress" property in dbus interface change back
to 0 and other properties will not reset to default value.
