* update enodes for ropsten and main clusters
* leave only 2 static nodes for ropsten and mainnet
* use different static nodes for mainnet
* specify static nodes from different hosts
Other changes:
* needed to patch that loop implementation in Discover V5 implementation in go-ethereum,
* fixed TestStatusNodeReconnectStaticPeers,
* fixed TestBackendAccountsConcurrently.
Previously we were doing 5 concurrent requests, thus it was
safe to tolerate 2 errors. With 4 it doesn't make sense to use
only 2 responses, because even if 1 of them is skewed - we will set
incorrect time.
We need to allow the user to specify custom BootNodes, the code has been
changed so that it will use the provided ones if passed through config
(or if they are empty). Othewise fallback on default ones.
* Heap queue stores only peers that were not added to p2p server
The primary goal of this change is to keep whitelist of peers
that are managed by topic pool while also preventing same peer
from being selected from heap queue multiple times.
This change makes invalidation mechanism more aggressive. With a primary goal to invalidate short living nodes faster. In current setup any node that became known in terms of discovery will stay in this state until it will fail to respond to 5 queries. Removing them earlier from a table allows to reduce latency for finding required nodes.
The second change, one adds a version for discovery, separates status dht from ethereum dht.
After we rolled out discovery it became obvious that our boot nodes became spammed with irrelevant nodes. And this made discovery process very long, for example with separate dht discovery takes ~2s, with mutual dht - it can take 1m-10m and there is still no guarantee to find a max amount of peers, cause status nodes is a very small part of whole ethereum infra.
In my understanding, we don't need to be a part of ethereum dht, and lower latency is way more important for us.
Closes: #941
Partially closes: #960 (960 requires futher investigations on devices)

add README
* update master key generations using "Bitcoin seed" as hmac key following BIP32
* use `"mnemonic" + passphrase` as salt for pbkdf2 following BIP39
* test generated addresses and compatibility with BIP44
* check generated public keys
* test children private keys
* update MasterKey to be a constant
* don't export salt and masterKey constants
* use `crypto.FromECDSA` to get the hex representation of the priv key
* use empty pwd for the generation of the BIP39 seed, keeping pwd to encrypt keys
* add comment before the seed generation with empty passphrase
* Make it possible to explicitly disable discovery
Discovery will be disabled in following cases:
- if there are not bootnodes - v5 server will be disabled
because there is no point in running it
- if user defined in config NoDiscovery=true this value will be preserved
even if we have bootnodes
So, basically discovery will be always enabled by default on mobile, unless
it is explicitly specified otherwise.
When statusd is used current behavior is that discovery is disabled by default.
I kept it in this change, but it would be better to change it.
* Fix leftovers
* Add wait group to peer pool to protect from races with p2p.Server
* Change fields only when all goroutines finished
* Turn off discovery after topic searches are stopped
* Don't set period to nil to avoid race with SearchTopic
* Close period chan only when all writers are finished
* add `-status` flag to enable the Status service
* remove status from default APIModules and add it only from statusd if specified
* remove AddAPIModule method
* allow -status flag values to be http or ipc
Some operations (like deploying contracts) require filter APIs to work.
Since these operations aren't supported on Infura anymore, and we don't
run LES, a separate implemenation of filters is required.
