joeduffy a2ae4accf4 Switch to parent pointers; display components nicely
This change switches from child lists to parent pointers, in the
way resource ancestries are represented.  This cleans up a fair bit
of the old parenting logic, including all notion of ambient parent
scopes (and will notably address pulumi/pulumi#435).

This lets us show a more parent/child display in the output when
doing planning and updating.  For instance, here is an update of
a lambda's text, which is logically part of a cloud timer:

    * cloud:timer:Timer: (same)
          [urn=urn:pulumi:malta::lm-cloud:☁️timer:Timer::lm-cts-malta-job-CleanSnapshots]
        * cloud:function:Function: (same)
              [urn=urn:pulumi:malta::lm-cloud:☁️function:Function::lm-cts-malta-job-CleanSnapshots]
            * aws:serverless:Function: (same)
                  [urn=urn:pulumi:malta::lm-cloud::aws:serverless:Function::lm-cts-malta-job-CleanSnapshots]
                ~ aws:lambda/function:Function: (modify)
                      [id=lm-cts-malta-job-CleanSnapshots-fee4f3bf41280741]
                      [urn=urn:pulumi:malta::lm-cloud::aws:lambda/function:Function::lm-cts-malta-job-CleanSnapshots]
                    - code            : archive(assets:2092f44) {
                        // etc etc etc

Note that we still get walls of text, but this will be actually
quite nice when combined with pulumi/pulumi#454.

I've also suppressed printing properties that didn't change during
updates when --detailed was not passed, and also suppressed empty
strings and zero-length arrays (since TF uses these as defaults in
many places and it just makes creation and deletion quite verbose).

Note that this is a far cry from everything we can possibly do
here as part of pulumi/pulumi#340 (and even pulumi/pulumi#417).
But it's a good start towards taming some of our output spew.
