add Associations endpoints change delay timer

When multiple associations that point to the same interface are
created, each change (adding or removing one) leads to updating
"endpoints" property on dbus. This property update is time consuming
with many endpoints already present, because each update needs to send
the whole list of current elements plus/minus one. With a lot of
changes in short time it can cause the service to be unresponsive.
This change adds timer to delay updating dbus property. This way many
associations updates can be aggregated into single dbus property
update.

Tested: Ran on hardware with dbus sensor tester. 4000 created sensors
with interfaces are processed within 10 seconds. Time before the change
was above 2 minutes.

Handle losing association endpoints

If the endpoint path of an association (not the path that has the
org.openbmc.Associations interface) goes off of D-Bus, then remove the 2
association objects and move this association to the list of pending
ones. That way if it ever comes back, the association objects will be
re-added.

This commit adds a moveAssociationToPending function in the code paths
where the mapper sees D-Bus paths going away. That function will find
all associations that involve that path, and then remove the actual
association paths and add them to the list of pending ones.

Add function to find assocs based on endpoint

The helper function findAssociations can find all
associations based on an endpoint path and return
enough information to recreate those associations
later.

For example, searching for something like "endpointA"

could return:
owner: "ownerA"
Association{"typeA", "typeB", "endpointB"}

Which implies the association:
endpointA/typeA -> endpointB/typeB

Check for pending associations

When the mapper is adding a new D-Bus path to its path map,
either via an introspect or in the interfacesAdded handler,
check if that new path has an outstanding pending association.

If it does, then create the 2 real association paths and
remove that entry from the pending associations maps.

Check for missing endpoints when adding assocs

An association links 2 D-Bus object paths together, one
which is the path that has the original associations
property, and another endpoint path. It's possible that
that endpoint path doesn't exist on D-Bus when that
associations property is created.

This commit, along with upcoming ones, adds support to not
create the actual association object paths until that
endpoint path shows up on D-Bus. In addition, if that
endpoint path were to get removed from D-Bus in the future,
then the association paths should be removed until that
path is back again.

This particular commit introduces the PendingAssociations map
to track these cases, and adds support in the associationChanged
path to add associations to this map if the endpoint path isn't
on D-Bus instead of just blindly creating the association objects.

Gather them into a structure to make it easier to write code to use
