Add SurrealDB template

[sandros94]

Add a template for SurrealDB (their Github repo)

A scalable, distributed, collaborative, document-graph database, for the realtime web.

I'm opening this after canceling of the related PR (#2617).
Mainly because of personal lack in php as well as a dependency for the #3976 feature request that add support for SSL to Databases. This is because SurrealDB should be exposed to the public by default, considering that all its communications evolve around HTTP/RPC endpoints (including those coming from the end-users).

Some of its key features to keep in consideration while adding it (all are controllable both via env variables or via args):

• Supports both system (database) and access (end-user) authentication. Also via external OAuth.
• Ability to store files locally (via RocksDB or SurrealKV), or remotely (FoundationDB, TiKV).
• Ability to enable or disable various capabilities (network requests, functions, scripts, public access).
• Requires a user and a pass during first creation for root.

For those who want to use it before this gets implemented you can refer to the original docker-compose.yaml from the PR.

this just would be awesome to have it as an official template. I got it working thanks to your PR tho!
