e26dc0a6e3 [#493] node/config: Fix corrupting of path to the subsection
In previous implementation `Config.Sub` method could lead to the violation
of the internal `path` slice because of `append`. This has been observed on
deeply nested subsections.

Fix `Config.Sub` to copy internal slice in order to prevent violations.
Cover problem case in test config files and unit test.

1aa88159ca [#493] node/config: Change Sub implementation
In some cases viper doesn't interpret `section.value` as a subsection with
`section` name, but value is value still can be accessed through full
pathname.

Fix `Config.Sub` method implementation in order to always interpret
configuration like described above as a subsection. From now method never
returns nil, therefore an additional check has been removed from the `Value`
method.

7e11bf9a55 [#493] cmd/node: Implement a basic configuration component
Create `config` package nearby storage node application. Implement `Config`
as a wrapper over `viper.Viper` that provides the minimum functionality
required by the application.

The constructor allows you to read the config from the file. Methods are
provided for reading subsections and values from the config tree. Helper
functions are implemented to cast a value to native Go types.
