Do not init caches for eACL, containers and netmap
if `disable_cache` config options is `true`, use
direct RPC calls instead.

Also use neo-go private key wrapper where possible, as it
already has methods for (un)marshaling.

Currently main chain's client is unused, therefore, it is not advisable to
require mandatory setting of addresses.

Calls to contracts by storage nodes do not lead to the accumulation of
multisignatures in the contract memory, so the call cost can always be
accurately calculated in advance without additional fee.

Client is configured simlarly to morph client.

Eigen trust block timer ticks to start new round of
eigen trust calculations. Every epoch this timer
recalculates duration and starts again.

Implement LRU cache of eACL tables read from sidechain. Use it as a netmap
storage in neofs-node app. Current cache size is set to 10 (constant).

Application should support several NEO endpoints so it can
switch between different RPC nodes when they fail. Application
iterates over endpoints in random order so the default list of
endpoints distribute workload kinda uniformly.

As in #72 storage application should behave the same way at remote
RPC node failures. The simplest way is to restart application. Later
we can reinitialize it without downtime.

Default values for capacity and price will be 0, so storage node
won't be present in placement. Add these attributes if they are
not explicitly set up by user config.

Well-known attributes set up with explicit configuration
values, other attributes set up from chain of attributes.
Chain of attributes is a string, that contains keys-value pairs,
divided by semicolon. Pairs itself divided by slash.
E.g. "StorageType:HDD/RPM:7200"

To run storage node at dev-env environment it should have
configurable parameters. To keep `cfg` structures we can
read configuration from env and yml config file with viper
and parse values such as script hashes, fees, keys into
`cfg` structures.
