Implement search

[eni23]

A feature that i currently miss is the possibility to search for things. Im not sure how easy this is to implement, but looks like another guy did something similar: https://github.com/Mykolaichenko/gotools/tree/master/vaulter

Bump, i really need that feature, as vc ls -r generates a horrendous amount of log entries

@aconitumnapellus since vault has no possibility to search, the vc had to do it same to get all secrets. there would be no improvement with the log situation.
