Client configuration (#4)

- added dependency on package `nette/schema`
- fixed structure of config schema for the compiler extension `ElasticaExtension`
- removed an option `compression` (the option is not defined in `ClientConfiguration` class)
- removed an option `log` (the option has been removed in version `7.0`)
- added an option `auth_type`
- updated examples in README
- options for the default (root) client and also options under a key `connections` are strictly defined in a configuration schema
- updated the configuration keys in README

 Extension does not pass any unset values to elastica so elastica defaults just work.
