Implementation of MariaDB container

[bitbrain]

This PR contains a slightly modified version of the MySQLContainer implementation due to the nature of MariaDB, which has its origins from MySQL.

@MyRealityCoding good idea - thanks. Will have a play and look over - but essentially would I be right in thinking this is just based on the MySQL module?

[bitbrain]

@rnorth Due to the historical nature of MariaDB this would make a lot of sense.

@MyRealityCoding absolutely, that's exactly right :)

I'm more looking to know what the differences are between this and the MySQL class, so I know where to look when reviewing!

[bitbrain]

The main difference is the naming (instead of using mysql, mariadb is used). Also for the tests itself different specific version numbers are used, see here. And not to forget about the test dependency for the mariadb driver.

My aim was to have an independent module on its own to be as free as possible. The problem is, since it is copied from the mysql module, if there was an issue in one module we would have to fix it for both, which makes it very fragile. What would you recommend? We could also provide the mariadb container inside the mysql module (as a "sub" category of mysql) and parameterize the JUnit tests and apply them for both containers. Another solution could be to inherit from the MySQL module. There would be the problem how to use the Junit tests from MySQL without copy-pasting them.

Miguel,

Thanks - that sounds fine to me.

Let me deal with the duplicated code issue after merging. Really, I think
that the majority of the duplication is in the tests. There's a lot of
boilerplate shared even in between completely different DB modules. I think
I might extract out the test code to another part of the codebase- that way
I think we might see a dramatic reduction in the volume of code in each
specific module.

Thanks for this!
