These changes add a support for syncing data between two Mail Servers. It does not give an easy way to start syncing. This will be solved in the next PR.
This change implements connection manager that monitors 3 types of events:
1. update of the selected mail servers
2. disconnect from a mail server
3. errors for requesting mail history
When selected mail servers provided we will try to connect with as many as possible, and later disconnect the surplus. For example if we want to connect with one mail server and 3 were selected, we try to connect with all (3), and later disconnect with 2. It will to establish connection with live mail server faster.
If mail server disconnects we will choose any other mail server from the list of selected. Unless we have only one mail server. In such case we don't have any other choice and we will leave things as is.
If request for history was expired we will disconnect such peer and try to find another one. We will follow same rules as described above.
We will have two components that will rely on this logic:
1. requesting history
If target peer is provided we will use that peer, otherwise we will request history from any selected mail server that is connected at the time of request.
2. confirmation from selected mail server
Confirmation from any selected mail server will bee used to send a feedback that envelope was sent.
I will add several extensions, but probably in separate PRs:
1. prioritize connection with mail server that was used before reboot
2. disconnect from mail servers if history request wasn't expired but failed.
3. wait some time in RequestsMessage RPC to establish connection with any mail server
Currently this feature is hidden, as certain changes will be necessary in status-react.

This commit updates geth to 1.8.17 and adds a possibility to enable metrics during compilation time.
The cascade of issues forced us to upgrade geth to 1.8.17 in order to allow enabling metrics during compilation time. 1.8.17 introduced `NodeID` refactoring and `enode` package which affected our peers pool and integration with Discovery V5.
* Implement subscriptions and filtering
* Add e2e test with log filter polling logs from EVM with clique backend
* Apply review comments
* Move devnode to t/devtests to avoid cycle in imports
- Replace command line flags with `-c` config flag. Part of #1180
- Convert node config private keys to hex-encoded string versions.
- Remove `GenerateConfig` from library.
- Remove unused `FirebaseConfig` from library.
- Fix loading of `config/status-chain-genesis.json` in non-dev machines.
In the current codebase if you want to use different keys (or any
other configuration) for tests it is required to place them at a
certain path in static folder, bundle them with go-bindata and only
then run tests. This is simply unnecessary.
This commit instead directs loads configurations from file without
relying on go-bindata
Remove `PendingSignRequests` queue from the sign module.
This closes#1027 by removing the pending sign requests queue dependency from the SendTransaction, SignMessage and Recover.

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.

This change adds adds an ability to use different source of time for whisper:
when envelope is created it is used to set expiry
to track when envelope needs to be expired
This time is then used to check validity of the envelope when it is received. Currently If we receive an envelope that is sent from future - peer will get disconnected. If envelope that was received has an expiry less then now it will be simply dropped, if expiry is less than now + 10*2 seconds peer will get dropped.
So, it is clear that whisper depends on time. And any time we get a skew with peers that is > 20s reliability will be grealy reduced.
In this change another source of time for whisper will be used. This time source will use ntp servers from pool.ntp.org to compute offset. When whisper queries time - this offset will be added/substracted from current time.
Query is executed every 2 mins, queries 5 different servers, cut offs min and max and the computes mean value. pool.ntp.org is resolved to different servers and according to documentation you will rarely hit the same.
Closes: #687
Every peer must be subscribed to the topic that is used to send messages.
In the test Alice was communicating with Bob and Charlie over custom topic, but
that topic wasn't added to a bloom filter, thus a certain flake was possible.
Normally it wasn't causing problems because syncAllowance in whisper, which is 10s:
- we set bloom filter to all zeros
- but we still will accept all envelopes for 10s
- in case we send first envelope into such channel after sync allowance - we will get an error such
that envelope doesn't match the bloom filter
