e45a2228dc objects: Erase the notion of connkey 
Make it explicit that all uses of this is actually the object
name. We already leaked this abstraction in several places so better
to make it explicit. This also communicates to users that this is a
field that is not immutable so it shouldn't be used as a unique key

d410773af8 virtManager: Remove virInterface polling 
There are no more users of interface objects in the code. Remove
all the polling support, and all the remaining references to
interface objects throughout the code base

419f8cd31b pollhelpers: Streamline usage a bit 
* Explicitly define the build 'cb', don't use lambda
* Rename pollhelpers arguments, clarifying use of cb
* Check support status in pollhelpers
* Move 'dopoll' checking up a level in vmmConnection

3ad646fef1 pollhelpers: Kill old style polling 
All the major hypervisor drivers have supported listAllDomains
since rhel6 vintage libvirt. Most other driver types have had the APIs
since their introduction, or for just as long.

I will be surprised if this affects anyone in any material way

f107e39989 Switch to more traditional logging structure 
Init a shared log instance in virtinst/logger.py, and use that
throughout the code base, so we aren't calling directly into
'logging'. This helps protect our logging output from being
cluttered with other library output, as happens with some
'requests' usage

48e32b429d Fix copyright header to specify GPLv2 or later, not GPLv2 only. 
The copyright headers in every file were chjanged in this previous commit

  Date:   Tue Mar 20 15:00:02 2018 -0400

    Use consistent and minimal license header for every file

Where before this they said "

  "either version 2 of the License, or (at your option) any later version."

Now they just say

  "GNU GPLv2"

This fixes it to say "GNU GPLv2 or later" again.

978fb25ac7 Wrap keys(), values() in a list 
In Python 3 dict.values() [1] , dict.keys() [2] and dict.items() [3]
return a view [4] of the dictionary’s values, keys and items.

In Python 2 these functions return a list. [5] [6] [7]

To resolve this we can convert the result of these function to a list.

b93cc3bbc9 pycodestyle: Do not use bare 'except:' 
A bare 'except:' catches all exceptions [1], including SystemExit,
KeyboardInterrupt, and GeneratorExit (which is not an error and should
not normally be caught by user code). In situations where you need to
catch all “normal” errors, you can catch the base class for all normal
exceptions, Exception [2].

838baf6946 connection: tick: Operate on combined object lists

having to pass around a ton of lists.

aefd4c4824 connection: Use name instead of uuid for object keys 
And clean up the API mess while we are at it. Treat the key as an opaque
value that users shouldn't depend on.

Besides the improved code clarity and API layout, this will help diagnose
'key error' issues, since we'll see an object name instead of UUID which
is hard to trace back.

ee7d0b620d connection: Support listAll* object lookups 
These calls save us a few API lookups, but are not supported by all
libvirt versions.

Since these bits were getting quite large, move them all to a separate
pollhelpers file.

However listAllInterfaces is returning an empty list for now, so we
disable the check: https://bugzilla.redhat.com/show_bug.cgi?id=982014
