/**
 * grpc config
 * @member Config#grpc
 * @property {String} dir - proto files dir, relative path
 * @property {String} property - default attach to `ctx.grpc.**`,与object.key同名,存在多个实例时需要配置该项
 * @property {Object} loadOpts - options pass to `grpc.load(file, type, opts)`
 * @property {Boolean} loadOpts.convertFieldsToCamelCase - default to true, `string user_name` -> `userName`
 * @property {Object} clientOpts - options pass to `new Client(host, credentials, opts)`
 * @property {String} endpoint - default andress to connect, for debug or showcase purpose
 * @property {Number} timeout - default 5000ms
 * @property {Boolean} clientSsl.enable - enable client ssl
 * @property {Buffer} clientSsl.rootCerts - The root certificate data file path,作为grpc client时仅提供该项作为证书即可
 * @property {Buffer} clientSsl.privateKey - The client certificate private key file path, if applicable
 * @property {Buffer} clientSsl.certChain - The client certificate cert chain file path, if applicable
 * @property {Object} clientSsl.verifyOptions - Additional peer verification options, if desired
 * @property {Object} clientSsl.options - 主要用于grpc.ssl_target_name_override和grpc.default_authority的配置
