Mainnet Release v1.2.7

This release is the final release from s3 branch to prepare the mainnet upgrade for the open staking rollout. There are a few bug fixes and some compatibility fixes of the mainnet.

This release contains an important viewID update (#2958) of the view change algorithm which is not fully backward compatible. This change won't impact any on-chain data though.

During the rolling upgrade, it is possible that the view change may happen/fail and we have to restart all harmony nodes to quickly upgrade all the nodes so to maintain consensus. This means the mainnet service may experience a short glitch during the restart process.

node runners please update the node.sh and harmony binary for this release.
The manual process to update your node is as follows:

curl -LO https://harmony.one/node.sh
chmod +x node.sh
./node.sh -v
v1 20200504.0

# stop your harmony process, either using `sudo systemctl stop harmony`
# or `pkill harmony`, `pkill node.sh`
# download the latest version of harmony node binary
./node.sh -I -d -S
mv staging/harmony .
./harmony -version
Harmony (C) 2019. harmony, version v5110-v1.2.7-0-g98bf1d10 (jenkins@ 2020-05-11T23:05:17+0000)

# restart your harmony process using your original way
