The main goal of this change is to remove async operations from node manager.
Additionally all of the signals from node manager are moved to status backend.
All of the async operation now will have the following behaviour:
- If node in the correct state exit immediatly without error
- If node not in the correct state exit immediatly with error
- In all other cases spawn a goroutine with wanted operation
- All the progress regarding that operation will be reported
by using signals
- Signals should be handled in once place, which is StatusBackend
There are 2 potentially breaking changes:
- Empty event field will be ommited when Envelope is sent to a client
- All errors will be delivered to a client as an Envelope, previously
some errors (NodeExists, NoRunningNode) were delivered synchronously

* fix sync-and-exit logic
* fix reading from doneSync channel
* clean up
* make statusd before using it
* move syncAndStopNode to different file
* change log level in travis chain sync command
* do not use fmt but log
* add progress log and set timeout to 20 mins
* set datadir to .ethereumtest
* fix datadir
Currently it is quite easy to introduce concurrency issues while working
with transaction object. For example, race issue will exist every time
while transaction is processed in a separate goroutine and caller will
try to check for an error before event to Done channel is sent.
This change removes all the data that is updated on transaction and leaves
it with ID, Args and Context (which is not used at the moment).

It is very unlikely that there will be 2 or more implementations
of tx manager and queue, as they are tailored specifically to status project
requirements.
- new EthereumTransactor that provides higher level API for working with ethereum network, and it is fully conformant with ethclient
- new test rpc service that improves flexibility and coverage of txqueue manager tests
- run complete transaction sequantially for each address
- go-ethereum: Get pending nonce from transaction pool
- add a patch with getting nonce from transaction pool
