There are two notifications:
- start estimation notification produced at the beginning of the
epoch,
- stop estimation notifications should be produced before
basic audit settlement starts.

This small refactoring adds `blocktimer.go` file with
all timer related function and constructors. This way
we can create all timers in one place (at the end of
innerring.Server constructor).
To do that we had to move timer reset into global
server state so it can be accessed by netmap
processor.

There is no point of making separate `Fee` and `NoFee`
wrappers because all reading operations are free disregarding
of fee value in static client. However we can use these same
wrappers so send transaction.

Calculate payments to storage nodes for the passed audit when changing the
epoch. The calculation results are wrapped in a call to the Balance contract
(one transaction per user-to-user transfer).

Implement component that analyzes audit results and generates transactions
for payment of awards for successfully passed audit. When calculating the
total fee, the declared price of the node (attribute) and the total volume
of storage groups, which were successfully audited by the container, are
taken into account. In one call the calculator processes all audit results
for the previous epoch (relative to the calculated parameter).

Pivot used to shuffle nodes in the CRUSH tree. This is

Netmap snapshot table caches bootstrap `AddPeer` txs so inner ring
node does not produce redundant approval txs for bootstrapped nodes.
However if node updates states to `Offline`, then such node should
be flagged in snapshot table, so re-bootstrap will actually produce
approval tx.
`ev.PublicKey.String()` returns uncompressed representation of the
node's public key, while snapshot contains compressed values.
Therefore the node was not flagged and re-bootstrap tx was not
approved by inner ring nodes.

Now alphabet contracts use signature collection to make

the same way as they vote fore new epoch or new container.

votes for one candidate from the list.

Large inner ring requires more gas to make container registration.
Container contract makes balance transfers for each inner ring node
and it require extra gas to execute. This estimation should be enough
