Subject: [PATCH] release: update the kata-deploy yaml files accordingly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's teach our `update-repository-version.sh` script to properly update
the kata-deploy tags on both kata-deploy and kata-cleanup yaml files.

The 3 scenarios that we're dealing with, based on which branch we're
targetting, are:
```
 1) [main] ------> [main]        NO-OP
   "alpha0"       "alpha1"

                   +----------------+----------------+
                   |      from      |       to       |
  -----------------+----------------+----------------+
  kata-deploy      | "latest"       | "latest"       |
  -----------------+----------------+----------------+
  kata-deploy-base | "stable        | "stable"       |
  -----------------+----------------+----------------+

 2) [main] ------> [stable] Update kata-deploy and
   "alpha2"         "rc0"   get rid of kata-deploy-base

                   +----------------+----------------+
                   |      from      |       to       |
  -----------------+----------------+----------------+
  kata-deploy      | "latest"       | "rc0"          |
  -----------------+----------------+----------------+
  kata-deploy-base | "stable"       | REMOVED        |
  -----------------+----------------+----------------+

 3) [stable] ------> [stable]    Update kata-deploy
    "x.y.z"         "x.y.(z+1)"

                   +----------------+----------------+
                   |      from      |       to       |
  -----------------+----------------+----------------+
  kata-deploy      | "x.y.z"        | "x.y.(z+1)"    |
  -----------------+----------------+----------------+
  kata-deploy-base | NON-EXISTENT   | NON-EXISTENT   |
  -----------------+----------------+----------------+
```

And we can easily cover those 3 cases only with the information about
the "${target_branch}" and the "${new_version}", where:
* case 1) if "${target_branch}" is "main" *and* "${new_version}"
  contains "alpha", do nothing
* case 2) if "${target_branch}" is "main" *and* "${new_version}"
  contains "rc":
  * change the kata-deploy & kata-cleanup tags from "latest" to
    "${new_version}".
  * delete the kata-deploy-stable & kata-cleanup-stable files.
* case 3) if the "${target_branch}" contains "stable":
  * change the kata-deploy & kata-cleanup tags from "${current_version}"
    to "${new_version}".
