[#175126219] Healthcheck step in pipeline

[balanza]

This PR introduces an healthcheck step just before promoting the staging slot to production.

Behaviour

• deploy application to Staging slot
• perform an http request against /info of the staging slot
• if the request is ok (code == 200)
  • switch slot with production
• else
  • abort the pipeline

Implementation

The implementation relies on this common template. The important concept is the http request is performed by a separate container which needs some configuration, please refer to the template repository for further info.

now that #116 is merged, do we need to disable autoswap in infra to merge & deploy this one?
