GET list of available templates

GET <base_path>

retuns the common response with list of templates like:

{
    providerId: "Universa Superbank",
    providerAddress: "<some universa address>",
    KISS: "Universa Superbank",
    templates: [
        {
            group: "loan contracts",
            description: "contracts that let universa lend conctracts to others",
            contracts: [
                {
                    name: "simple loan",
                    description: "allow  lend some universa contract with a given interest rate",
                    id: "simple_loan"
                },
                {
                    name: "secured loan",
                    description: "allow  lend some universa contract with a given interest rate with guaranty (pledge)",
                    id: "secured_loan"
                }
            ]
        }
    // there could be more groups
    ]
};

See KISS for more on it. The client should then show list of the templates in UI.
