This commit allows installing a package when a different version is
already installed. Currently, if the package is installed globally (the
only option) - it will overwrite the previous version reference.
A followup change will allow installing into environments to work around
this limitation.

Part of #660

Also:

* Add PackageManager.IsInstalled - fuzzy-match installation check for packages, without parsing their manifests

Add docker image resolver to `param set`

Adds an image resolve to param set. eg:

`ks param set deployment image foo/bar:latest`

uses the docker registry to find the manifest reference for `foo/bar:latest`.
It then sets this value instead. Support is at the component and environment
level.

Fixes #569

Add versioned, environment-scoped package support

This change adds version-mapped package support to environments. An environment can specify the specific version of a package to consume - and multiple, side-by-side versions of a package can be installed in the package cache.

Closes #631
Closes #651

* Deprecate GitVersion from LibraryConfig
* pkg.Descriptor.Part -> pkg.Descriptor.Name
* Add Version, Path to PackageManager.
* Composed package structs
* Revendoring - Tailor import path to environment's packages, allow version-free import strings
* Skip unversioned packages when revendoring
* Allow injection of custom importers into jsonnet.VM wrapper
* Allow passing VMOpts to VM via Evaluate*
* Add versioned package evaluation test
* Allow versioned packages to fall back to unversioned paths
* Fix DefaultInstallChecker shadowed variable when looking up environment packages
* Test skipping of missing paths in revendorPackages
* Tweak CacheDependency->ResolveLibrary interface - onFile paths should always be relative to the registry root
* Ensure 0.2.0 version is output when re-writing app.yaml

Retry apply if conflict is detected

When applying objects to a cluster, there a small chance that a
conflict could arise. Instead of failing instantly, sleep for one
second, and retry up to five times.

Ksonnet will warn if ksonnet-lib is in the legacy location and the
user can use `ks upgrade` to move the files to their new location.
