Get/Update DomainAsyncWorkflowConfiguraton methods in admin API and CLI

[taylanisikdemir]

What changed?
Continuing from where I left in #5608. Admin API methods GetDomainAsyncWorkflowConfiguraton and UpdateDomainAsyncWorkflowConfiguraton are implemented and corresponding CLI tool commands are exposed.

Next steps:

• DB schema changes on DomainConfig type to make this work e2e
• Complete changes in config.go.

How did you test it?

• Unit and integration tests to validate nothing is broken
• Tried new API via new CLI commands
  Get example:

go run cmd/tools/cli/main.go admin aq get \
  --domain samples-domain

Put example:

go run cmd/tools/cli/main.go admin aq update \
  --domain samples-domain \
  --json "{\"PredefinedQueueName\":\"yoyo\"}"

Do you mind adding the tests?

this test body is not ideal. I will convert this to proper table test and simplify the body in a follow up PR
