In accordance to the upstream release cycle, we now provide 2 flavours
of the percona mysql ecosystem. The default is the LTS variant,
additionally there is now the floating `percona-server_innovation`
always pointing to the most recent regular release.
- mentioned in release notes
- adapted all depending tests and tools (xtrabackup)
This release belongs to the "innovation" release track of Percona,
making it likely to diverge over time from the LTS release. Hence I just
created a separate packaging expression for this.
