Move common modules into separate repositories

[ma-sch]

Some of the common modules in the SLM core repository have become quite large and are also increasing the time required for the build pipeline. Such modules should be moved to separate repositories and published to Maven Central. Relevant modules are:

• common.aas
• common.awx
• common.consul
• common.vault

Additional context
Permission to upload to Maven Central has already been granted: https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/7158#note_6357907
