IF pipeline exists do not try to create

[LiliamLeme]

When running the deployment, there is the need to check if the azdo pipelines were previously created and delete them if so.
If pipeline exists - needs to be delete before attempting to create it again.
The change will be in this script deploy_azdo_pipelines.sh.
The goal is remediate this error that happens if the deploy runs twice.

• github_sc_name=mdwdops-github
  ++ jq -r --arg NAME mdwdops-github '.[] | select(.name==$NAME) | .id'
  ++ az devops service-endpoint list --output json
• github_sc_id=23eefba5-4e29-4f66-acac-4e922b43e75a
• createPipeline ci-qa-python 'This pipeline runs python unit tests and linting.'
• declare pipeline_name=ci-qa-python
• declare 'pipeline_description=This pipeline runs python unit tests and linting.'
• full_pipeline_name=mdwdops-ci-qa-python

DoD

• Alter deploy_azdo_pipelines.sh to delete pipelines if already created and deploy them again.
