(MODULES-1143) Add package_manage parameters

[juniorsysadmin]

This patch adds a package_manage parameter for both mysql::server and mysql::client

i'm really having trouble comprehending the motivation behind this ticket/pr.
this adds so much complexity on top of something that should be really simple: "a puppet module named 'mysql' installs and manages mysql. [period]"

ping @hunner bc you approved of the ticket ;)

[juniorsysadmin]

I don't have any strong feelings on this PR either way. However, I can guess that at least one of the motivations for the person who raised the ticket would have been the MySQL forks that are floating around (and will probably increase given public statements from Oracle). Percona has its own module on the Forge already, although one could argue that it differs from MySQL enough to need one.

[Micsi]

I would like to argue that the module is tagged with percona on the forge but is not able to work with it at this time. With this PR integrated one would be able to install percona (or MariaDB) and have it managed by this module.

It would make it possible to get an existing server under Puppet control more easily which is a big plus in my eyes.

[igalic]

@Micsi it's possible, even now, to install and manage (mostly…) MariaDB.

@juniorsysadmin would you mind rebasing this pull request?

[juniorsysadmin]

@igalic Rebased. I also fixed the arrow alignment lint issue introduced by 5f62e6d . Hope you don't mind.

[Micsi]

@igalic unfortunately, it's not really choosable... the module uses MariaDB on some versions of some distros (as to params.pp). The user is not involved.

Again, I would see this a big plus for several reasons:

• Give me control of what flavour of MySQL to install
• Take over an existing MySQL-Server
• Give me better control of when and what to update.

To the last point: I have my systems upgrade automatically using puppetlabs-apt unattended-upgrades. Some important pieces are hold, notably the databases as upgrades of those involve a server restart

Thanks @juniorsysadmin !
