[EDGEHOG] This commit allows backward  compatibility of custom projects

* Since the Clea OS rebranding of the project some of the custom
projects build are actually broken because they are still pointing
to the old 'Edgehog OS' brand and the old 'edgehog' tagged recipes.
* Extend the usage of the SECO_REMOTE variable in order to become as
much as possible independent from the name of the Yocto project and
allow backward compatibility.
* This commit refers to Jira ticket: CLEAOS-442

* The Azure blob storage folder organization easily allows to retrieve
the software artifacts without the necessity of having 'latest' tagged
ones.
