DS-2400 Integration Test and Unit Python package Bug (#1011)

# Task Branch Pull Request

**<https://nhsd-jira.digital.nhs.uk/browse/DS-2400>**

## Description of Changes

This fixes an issue with a python package after an update to a
dependency removed a underlying function. Fixed by removing pytest-bdd
package version pinning.

Also included in this PR is a temp fix for the build image codebuild
jobs. A 20 second sleep has been put in place to give time for the aws
ecr security image scan to be ready, before it's checked.
