Security: (non critical) user passwords should be salted

[Nicola Migone]

If my understanding of the code is correct, here is where the user is created:

skytable/server/src/engine/core/system_db.rs

Line 141 in 548f806

 let password_hash = rcrypt::hash(password, rcrypt::DEFAULT_COST).unwrap(); 

and it seems like the password is not salted anywhere.

I understand that, because operating a database is usually only allowed to competent people, the risks of not salting are very minimal; however, given it has a very small impact on speed, I believe it would be benefical to implement it.

I volunteer to implement it, if it gets approved.

Hi, all passwords are hashed and salted based on the bcrypt algorithm using rcrypt
