Update modules: Application update modules OOTB

The first iteration of the update modules framework (MEN-2000) target application updates. To have any value to the user, update modules doing the actual installation must be available. Users can write them themselves, but we need to provide some that are readily available in order to improve getting started and testing experience.

User value (why)

• Easy evaluation of application updates with existing update modules for the most common application update use cases

Size (SP)

• 28

Acceptance criteria

• Update modules covering these application updates are available: single file(s), rpm packages, deb packages, shell command, set of docker containers
• The above five update modules are out of the box: they are part of the default installation of Mender on all platforms (meta-mender, mender-convert, etc.)
• Payload generation happens through separate scripts
• There is a Mender Hub article for each of the above five update modules
