Parse server version from GitVersion

We currently attempt to parse the server version from the Major / Minor
version provided by client-go's ServerVersion object. It is not always
the case that these fields are populated; and is more accurate to use
the GitVersion.

Resolve api spec based on swagger version

Currently the warning is only displayed on 'apply'. Other commands
should also show this warning. Logic should also be handled internally
instead of being exposed at the interface level.

Currently the Kubernetes API version used is defaulted to 1.7.0 if the
--api-spec flag is not populated. This change will attempt to retrieve
the swagger.json version of the server instead.

Set param boolean types as strings

Fixes #311

There currently exists a discrepency between the param types expected
from:
1. The parts library and in generate / prototype use
2. ks param set

ks param set will set boolean types as jsonnet boolean types, however,
prototypes will set boolean types as strings (i.e. in quotes). This
change will make it such that ks param sets boolean types as strings.
The reason we're not setting booleans in both model is because that will
require a better dependency story around ksonnet/parts first.

Fix bug with invalid base.libsonnet import path

Signed-off-by: bryanl <bryanliles@gmail.com>

There exists a bug in the reference path of base.libsonnet for nested
environment directories. We are referencing a hardcoded import
"../base.libsonnet". The works for top level environment directories but
obviously does not work for nested directories.

This commit will add the environments directory as a global lib path.

App spec to take a single destination

Signed-off-by: Jessica Yuen <im.jessicayuen@gmail.com>

Currently the app.yaml spec takes a list of destinations. The change
exists to anticipate support for an environment supporting multiple
clusters or "destinations". The problem is, while the use case makes
sense for `apply`, and `delete`, it becomes ambiguous which cluster is
being referred to during commands such as `diff`. We've considered
specifying a cluster during a `diff`, however, ks currently doesn't have
a notion of a cluster identity. This change is to update the app.yaml to
take a single destination to more accurately represent the state of
things.

Add warning for running deprecated ks app against ks >= 0.9.0

This is a temporary piece of code that should be removed after 1.0.0.

This warning exists to tell users that are using ks < 0.9.0 with the
dated environments model (contains the 'spec.json' file), to migrate to
the newer 'app.yaml' model.
