Support for official mysql 8 packages

[waynegemmell]

I've added support for the official mysql 8.0 packages and the relevant repositories.
Package names are mysql-community-server and mysql-community-client.
I know the repo setting breaks convention a bit but it is compulsory so I'm not sure how else to properly include it.

This change requires the salt pull request I created saltstack/salt#51240 to be able to grant users.

wasn't there an issue with mariadb-server which has the same debconf settings as mysql-server?
see: #160

[waynegemmell]

I'll revert that change, it wasn't really necessary after I realised that mysql-community-server has it's own set of debconf settings.

In #186 I added standardized mapping files but unfortunately skipped the codenamemap.yaml. This PR suggests its needed.

Hi @waynegemmell any chance you could introduce a codenamemap.yaml for this PR?

[waynegemmell]

I'll have a look at the codenamemap.yaml. Not sure what that entails. I'll let you know if I can't come right.

[waynegemmell]

Sorry, can you please explain the purpose of the codenamemap.yaml file in this context?

[noelmcloughlin]

I understand the purpose of the codenamemap is to handle OS release specific differences. So if you need to handle an official repo from some distro this method scales best.

                merge=salt['grains.filter_by'](
                    osfamilymap,
                    grain='os_family',
                    merge=salt['grains.filter_by'](
                        oscodenames,
                        grain='oscodename',
                        merge=salt['pillar.get']

Here are three examples of implementations people done.

$ for f in $( find . | grep codenamemap ); do echo $f;cat $f; done
