unit-test: Debug functions to dump data structures

Visualizing the key data structures in objmgr can be very useful for
debug and for writing test cases

Example output when new function called:
 ##### interface_map_type #####
------------------------------------
OBJ PATH:      /xyz/openbmc_project/test
DBUS SERVICE:   xyz.openbmc_project.Test
INTERFACE:        org.freedesktop.DBus.Introspectable
INTERFACE:        org.freedesktop.DBus.Peer
INTERFACE:        org.freedesktop.DBus.Properties
------------------------------------
 ##### AssociationOwnersType #####
------------------------------------
OBJ PATH:      /xyz/openbmc_project/test/xyz
DBUS SERVICE:   xyz.openbmc_project.Test
ASSOC PATH:      /xyz/openbmc_project/inventory/system/chassis/error
ENDPOINT:         /xyz/openbmc_project/test/xyz
ASSOC PATH:      /xyz/openbmc_project/test/xyz/inventory
ENDPOINT:         /xyz/openbmc_project/inventory/system/chassis
-----------------------------------
 ##### AssociationInterfaces #####
------------------------------------
OBJ PATH:      /xyz/openbmc_project/inventory/system/chassis/error
ENDPOINTS:      /xyz/openbmc_project/test/xyz
------------------------------------
