add SoliDB as database

[solisoft]

Hi there,

SoliDB is a new DB inspired by ArangoDB but free (O'Sassy licence)
I use it on my soliMVC framework.
The purpose of the DB is to be very modular (multi documents) and fast. It can embed Lua scripts for kinda stored procedures, host blob content, it can be configurated as Master<->Master DB (supporting sharding)

I made a PR for that here #10740 (comment)

Please let me know what should I do to allow you to add it.

Thanks
