rubenv/sql-migrate -> golang-migrate tool

[musinit]

Is your feature request related to a problem? Please describe.
We use sql-migrate (https://github.com/rubenv/sql-migrate) in our projects and we want to migrate to golang-migrate. We have a lot of migration files that we need to re-create for go-migrate format (with .up.sql, .down.sql postfix)

Describe the solution you'd like
Lib utils that would

• rewrite migrations -> migrations-legacy
• create a new migrations folder and re-create old migration files in a new format for go-migrate

Describe alternatives you've considered
Write this tiny util manually

Additional context
I am sure that would help a lot of teams to move from other migration tools to this one and make this library more popular.
We can implement migration tool for other libraries as well.

This is out of scope for this project and would unnecessarily complicate the build pipeline.
The migration tool sounds useful so I encourage to build and open source it. Once you've done so, we can link to it in our docs.

Ok, I will do it.

@dhui I did It:)

I think I can improve this one and add more sources for golang-migrate

[musinit]

Just added more sources: dbmate and goose

Updated the README to mention migradaptor
