Code review comment for lp:~hatch/juju-gui/bundle-fail-gracefully

*** Submitted:

Bundle topology rendering fails gracefully

If the bundle does not provide proper xy position annotations
on any of the services in its deployer file we do not render
the bundle topology and instead remove the bundle topology
tab, selecting the Charms tab to show the charms the
bundle contains.

Because we don't have any bundles with proper positions right
now I added the flag `strictBundle` to enable this feature.
