Iterate Calls without validation

[Ravi8308]

Current Behavior:

Iteration not possible without adding validation

Currently code is written like this for achieving iteration
version: 2
requests:
maxRetries:
request:
url: https://postman-echo.com/time/now
method: GET
delay: 900
maxRetries: 30
validate:
- jsonpath: status
expect: 200
- jsonpath: content
expect: <$ Env("STREST_GMT_DATE") $>

Expected Behavior:

Iterates Call when validation is not defined and Iteration is added

version: 2
requests:
maxRetries:
request:
url: https://postman-echo.com/time/now
method: GET
delay: 900
maxRetries: 30
iteration : 20
