sensors: Remove sensor manager

This sensor manager was in charge of creating the
/org/openbmc/sensors object and initializing them, but this path
is now deprecated and the sensors have moved to other paths
specified by the ipmi sensor config.yaml file in the
openbmc/openbmc repo. This sensor manager can now be removed.

Tested: Powered on a Witherspoon to the Host OS without ipmi
giving get/set sensor errors.

pathtree: Make dataitems() use the cache dict under restricted args

This achieves a 100x improvement in iteration time when the subtree
rooted at the root of the full tree and there is no depth limit (i.e.
the caller has requested all "populated" items). Whilst it sounds like a
restricted case, it is a very common query by way of phosphor-objmgr's
obmc/mapper/server.py:ObjectMapper.process_old_owner()

Note this is a quasi API break, as some keys that were previously
not present in the results may now appear: Explicitly storing 'None'
into the data structure will have the key with 'None' appear in the
full-tree dataitems() case. However, given this was filtered previously,
no existing callers should be storing 'None' into the tree as they would
not have been able to retrieve it via dataitems().

pathtree: Allow get() on subtrees

When running recent PathTree modifications on a BMC we can see failures
in the log such as "Failed to invoke ObjectMapper method" from the
phosphor-fru-fault-monitor. This can be triggered via the
openbmc-test-automation suite, for example with the following command

$ robot -v OPENBMC_HOST:w5.aus.stglabs.ibm.com --include \
Create_Test_Error_Callout_And_Verify extended/test_association.robot

Capturing the DBus traffic across this test case
(`busctl capture > dbus.pcap`) and analysing it with Wireshark showed the
following method invocation:

These packets translate to the following `busctl` invocation and response:

```
root@witherspoon:~# busctl call \
xyz.openbmc_project.ObjectMapper \
/xyz/openbmc_project/object_mapper \
xyz.openbmc_project.ObjectMapper \

1 \
org.freedesktop.Dbus.ObjectManager
path or object not found: /xyz/openbmc_project/led/groups/
root@witherspoon:~#
```

From `busctl tree` we can see that the objects do actually appear on the
bus:

root@witherspoon:~# busctl tree
...
Service xyz.openbmc_project.LED.GroupManager:
└─/xyz
└─/xyz/openbmc_project

├─/xyz/openbmc_project/led/groups/core0_fault
├─/xyz/openbmc_project/led/groups/core10_fault
...
```

However, the /xyz/openbmc_project/led/groups/ path represents a subtree
root, not a leaf element. I didn't realise this was a supported
use-case, and over-aggressively removed support for it in the recent
patch adding the flat dict cache.

Add in a fallback to iterating the PathTree datastructure when we take a
cache miss.

Point PowerSupplyRedundancySensor to new interface

The PowerSupplyRedundancy sensor is used by the Host to know
whether the system has redundant power supply support.
The sensor is implemented under the legacy openbmc/pyphosphor
repo which does not persist it's values. This commit will
move this sensor into the official phosphor settings repo
(which does have persistency support) but also keep the legacy
interfaces in place for backwards compatibility.

The PowerSupplyRedundancySensor should look at the new
PowerSupplyRedundancy interface for its value and when
setting the PowerSupplyRedundancySensor, set the new value.

The string "org.freedesktop.UnknownInterface" is not an

*.DBus.Error.* so change this error string to the right one.

Also fix the error responses when dbus errors are raised.
