docs: note MariaDB support in README

[robertsilen]

Summary

Documents that CloudStack uses a MySQL-compatible database. The Docker development setup in tools/docker/docker-compose.yml uses MariaDB (mariadb:10.0); the README only mentioned MySQL in the cryptographic software notice.

Documentation only; no code or deployment changes.

Test plan

• README only

@robertsilen, thanks for the PR!

@robertsilen, do you think it is required to mention that The Docker development setup in tools/docker/docker-compose.yml uses MariaDB? I think that only mentioning that both MariaDB and MySQL are supported would be enough here

I think that something like this would be better:

* CloudStack requires a MySQL-compatible database (MariaDB or MySQL), and uses native database encryption functionality.

@bernardodemarco@winterhazel Thanks for the review — agreed. I've dropped the Docker compose reference and simplified the line to:

CloudStack requires a MySQL-compatible database (MariaDB or MySQL), and uses native database encryption functionality.

Pushed to the branch.
