* [p2p/pex] connect to more than 10 peers

also, remove DefaultMinNumOutboundPeers because a) I am not sure it's
needed b) it's super confusing

look closely

```
maxPeers := sw.config.MaxNumPeers - DefaultMinNumOutboundPeers
if maxPeers <= sw.peers.Size() {
  sw.Logger.Info("Ignoring inbound connection: already have enough peers", "address", inConn.RemoteAddr().String(), "numPeers", sw.peers.Size(), "max", maxPeers)
```

we print maxPeers = config.MaxPeers - DefaultMinNumOutboundPeers. So we
may not have enough peers even though we say we have enough.

This adds an ADR entry addressing the implementation of a `ProposeTx`
method in the ABCI proposed in #1776. Fundamentally, this proposal gives
some control of block proposals to the application. The initial use case is
to support the Minimal Viable Plasma specification.

* ADR: Proposal for multisignature encoding

This proposal is partially tied to the resolution of #1957.

* Change title to Encoding standard for multisignatures

* ADR: Change multisigs ADR now that amino must be used for pubkeys

* Address PR comments

Refs #1134

Validation:

- ignored in block.ValidateBasic since it's stateful information
- checked in blockExec.ValidateBlock

Refs #1712

* change validators to last_commit_info in RequestBeginBlock
* do not send pubkeys with RequestBeginBlock

Refs #1856

Previously you could not assume that your transaction hash would
appear on chain.

This PR changes ABCI time format from int64 (Unix seconds) to WKT (WellKnownType) google.protobuf.Timestamp.

Refs #1857

Reasons:

better precision
standard DT for proto

* update Gopkg.lock
* [makefile] remove extra grep
    - go list excludes vendor by default now
* proto3 timestamp
* [docs/abci-spec] note about serialisation format
* make time non-nullable

* p2p: Propose PeerTransport ADR
* adr: Set status to in review
* adr: Add high-level decision
* adr: Extend on the idea of guards
* adr: Rework guards into transport specific filters
* adr: Rename to nodeAddr
* adr: Incorporate review

This now uses one hkdf on the X25519 shared secret to create
a key for the sender and receiver.
The hkdf call is now just called upon the computed shared
secret, since the shared secret is a function of the pubkeys.

The nonces now start at 0, as we are using chacha as a stream
cipher, and the sender and receiver now have different keys.

Refs #1861

We don't use the fee field and its likely just confusing.

We can add backwards compatible priority (instead of fee) later.

Note priority is better than fee because it lets the app do the math on how to rank order transactions, rather than forcing that into tendermint (ie. if we return fee, priority would be fee/gas)

Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.

Closes #1956

* Add private peer ID tracking to AddrBook

* Remove private peer tracking/blocking from pex

* debug level msg when we fail to add private address

* config: 10x default send/recv rate

This increases the default send/recv rate from 512 kB/s to 5.12 mB/s

Closes #1752

* Fix typo

* docs: deprecate specification dir, closes #1814

* update genesis

* old spec dir, deprecation complete

This reverts commit d02c5d1e30.

* limit the number of requests in flights for Prometheus server

Closes #1804

Default to 1 because usually there's just one collector.

* config: Up default for prom connections

* include ecosystem.json

* update changelog

* also include zarko's interview
