MariaDB support

[pbstriker38]

Would like automatic instrumentation for the MariaDB package.

https://www.npmjs.com/package/mariadb

I've forked the repo and am looking into how difficult this would be to implement.

We are moving off of MariaDB so this is not a priority for us anymore. We implemented our own instrumentation using Sequelize hooks.

const sqlSummary = require("sql-summary");

sequelizeClient = new Sequelize(dbConfig);

sequelizeClient.addHook("beforeQuery", function(options, query) {
    const dbSpan = tracer.startSpan(
        null,
        { tags: { type: "db", subtype: "mariadb", action: "query" } }
    );
    options.context = { dbSpan: dbSpan };
});

sequelizeClient.addHook("afterQuery", function(options, query) {
    if (options.context.dbSpan) {
        if (query.sql) {
            options.context.dbSpan.setOperationName(sqlSummary(query.sql));
            options.context.dbSpan.setTag("query_string", query.sql);
        }

        options.context.dbSpan.finish();
    }
});

I create a functional PR (#4045) we have be using in production since. No one review it and merge, I ask for it but no one answer.
