Extension Manager Upgrade Extensions

[rdig]

This PR adds in the ability for the Extension Manager to be able to upgrade currently installed extensions

In order to save time, this PR cherry-pick commits 0e3c3ff 54cd6d9 and 4acd0d2 from #2413

Changes

• use the new version 4 of colonyJS
• add ExtensionUpgrade subcomponent
• add colonyExtensionUpgrade saga
• add resolver to fetch the latest extension version from the network
• refactor extension to display correct version

To test the extension version upgrade

(make sure to run npm i and `npm provision first)

ColonyNetwork:

• After the stack was started
• Checkout colonyNetwork to commit 840e378c (I used a separate repo, but I guess the one in src/lib/colonyNetwork works fine as well...)
• yarn (to install packages)
• run yarn run truffle exec ./scripts/deployOldExtensionVersions.js

Dapp:

• inside src/modules/dashboard/sagas/extensions.ts, change line 96 from:

params: [getExtensionHash(extensionId), networkExtensionVersion],

to

params: [getExtensionHash(extensionId), 1],

• install the "Voting Reputation" extension (either this or Coin Machine, they are the only ones that have version 2 available)
• Enable it
• Upgrade it
• 🎉

DEV-257 Extensions Versions Upgrades

This issue will refactor both colonyJS and the Extensions Manager in order for them to support extensions contract upgrades.

On the colonyJS side, we need to introduce both a way to generate the new version abis and factories, as well as the logic to make the extension clients aware of versions.

On the Extension Manager side, we need some minor UI, resolvers and sagas in order to be able to upgrade the extension client to the new version.
