Feature request for core-api wallets/search

[dutchpool]

It doesn't look like you can query the wallets/search api with power or stakePower params yet.

I could use this functionality if it worked similar to balance:

        balance: Joi.object().keys({
            from: Joi.number().integer(),
            to: Joi.number().integer(),
        }),
