MySql Database provider

[unaizorrilla]

We can add more database providers to Esquio V4 with new generic database provider contributed by @Kronos11 . MySql and Oracle are some of the most important/frequent db providers for .NET developers.

Adding new provider include following tasks:

• Add new context for MySql
• Add migrations and new Design Context Factory
• Modify docker compose infra to include my sql
• Include new provider on DbAdapter for Respawn
• Modify build.ps1 and build.sh to execute tests on this new provider
• Modify github actions to include this db on all functional tests execution
