Changed the setting to use latest release versions for every image by…

… default.

• istio adapter and installer images converted to release images.

Using 'latest' is always a bad idea - it's a source of waste
How will the person debugging an issue know precisely what "latest" meant when the issue occurred?
Without wasting time guessing, assuming, etc?

Agree on shortterm for the MVP, but would like we create a JIRA where we start using actual versions everywhere.

[bgokden]

@jason-magnetic-io these are the default values. Users can set versions in config.yml while installing.

vamp install --configuration ./config.yml --certificate-output-path ./cert.crt

config.yaml used in test:

rootPassword: $ROOTPASSWORD
databaseUrl:
databaseName: vamp
imageName: $KUBIST_IMAGE_NAME
repoUsername: $REPO_USERNAME
repoPassword: $REPO_PASSWORD
imageTag: $KUBIST_IMAGE_TAG
mode: IN_CLUSTER
istioInstallerImage: $ISTIO_INSTALLER_IMAGE
istioAdapterImage: $ISTIO_ADAPTER_IMAGE

I also like versioned images, but I also don't want to update defaults every day.
I am open to recommendations.
