Make docker creds section in network.yaml as optional in Hyperledger Indy

[TheJagpreet]

Currently, we don't have an option to exclude docker credentials from network.yaml
The docker credentials are used to create a kubernetes secret (docker cred template) which is used to pull images with docker credentials.
With the inclusion of images over a public dockerhub registry, we dont need the docker username & password section in the network.yaml, the regcred and thus there is no need to pull the image with docker creds.

The changes required are:

• In the file hyperledger-indy/configuration/roles/create/imagepullsecret/tasks/main.yaml, change the first task named "Check for ImagePullSecret for {{ organization }}" and the next task named "Create the docker pull registry secret for {{ component_ns }}" to run only if network.docker.username && network.docker.password are defined and are not empty. To check if a variable (network.docker.username) is defined and not empty, you can use the code network.docker.username | default('', true) | trim != ''

• For the charts, you need to a put a condition to use imagePullSecrets only when network.docker.username | default('', true) | trim != '' and network.docker.password | default('', true) | trim != ''

  The following charts are required to be changed for Hyperledger Indy

  • indy-auth-job chart

  • indy-key-mgmt chart

  • indy-ledger-txn chart

  • indy-node chart

• Test the network with the above mentioned changes

I would like to fix this issue. Can I raise a PR for this?
