Add support for SingleStore DB

[rzv-me]

Hi,

It would be awesome to be able to deploy SingleStore DB using coolify.

https://www.singlestore.com/

SingleStore can be run with a free license key for the self managed tier for up to 4 leaf nodes, each of them with 32GB Ram.

What is included in the free version of SingleStore Self-Managed?
SingleStore offers a free tier for clusters up to four (4) nodes (not including aggregator nodes) and up to 128 GB memory capacity. Unlike other database providers, the free version of SingleStore is fully featured and includes all the performance, security and capabilities available in any version of our database. There are no time or deployment restrictions.

thanks
