Dedicated type `LoggerSection` turned out to be redundant since it doesn't
do a hidden logic and just uses `config.Config` API.
Remove `LoggerSection` type and implement `Level` which do the same.

In previous implementation ENV values were read only if config filepath is
specified. From now ENVs are always read to `Config`.

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.

Create `logger` sub-package of `config` package. Implement `LoggerSection`
type of logger sub-section. Add `Level` method to read logger level config
value. Default level is `info`.

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.

Container sessions allow to perform some operations on behalf of another
user. There is a need to to attach session tokens to commands.
Add `session` flag to `put`, `delete` and `set-eacl` commands from
`container` section. It should be a path to the JSON-encoded session token.

Token of the container session should be written out with container context.
The context should have the verb corresponding to the operation. If an
operation is performed on a fixed container, the session should be
propagated to it or to all user containers
Implement all described checks in validation of `Put` / `Delete` / `SetEACL`
events.

In previous implementation verification of `SetEACL` events failed on events
without session token. It was caused by redundant tries to verify `nil`
session token.

Implement function `fatalOnErrDetails` similar to `fatalOnErr` but accepting
string details that are written to log output. Use the function everywhere
in application code without wrapping in an if-else statement.

Session token can be presented `Put`, `Delete` and `SetEACL` notification
events. IR should consider this case as issuing a power of attorney to a
third party. Thus, checking the eligibility for an operation should be
complicated:
- token owner should be the owner of the related container;
- the intent must be signed with a session key;
- the power of attorney must be signed by the owner of the container.
Omitted checks (TBD):
- session token should have container session context;
- the verb of the context should correspond to the operation.

There is no TLS protocol support in
