State defines which state the current deployment is in.
Values:
STATE_UNSPECIFIED (0):
Unspecified state.
DRAFT (1):
A deployment starts in DRAFT state. All edits
are made in DRAFT state. A deployment opened for
editing after applying will be in draft state,
while its prevision revision will be its current
applied version.
APPLIED (2):
This state means that the contents (YAML
files containing kubernetes resources) of the
deployment have been applied to an Orchestration
Cluster. A revision is created when a deployment
is applied. This revision will represent the
latest view of what is applied on the cluster
until the deployment is modified and applied
again, which will create a new revision.
