Migrate to use Metamask v8 or v9

Added

• Changes to add compatibility with latest Metamask versions (currently v8.1.11 and v9.0.4)
• BREAKING CHANGE use [email protected] as peer dependency
• BREAKING CHANGE only node >=10.12 and node < 11 support for building this package.
• Option to approve all accounts when connecting from Dapp for the first time (is very difficult to get to this modal once an account is connected because Metamask remembers this decision and only connects to that account. If you want the switchAccount method to work, you need to authorize all accounts when connecting for the first time)

Chore

• Bump devDependencies

How to review this PR?

Most of the file changes are under metamask folder. I've just added the corresponding zips from latest v8 and v9 Chrome versions. Once we scroll below metamask folder files we can check the real changes that were applied to the project

Recommended to publish using a major version v2.0.0

Hey guys, thanks for the PR, i’m currently on vacation, but next week i’ll test and merge/release this if all’s good.

Although there are few minor issues with the checkbox's on the Metamask v9. It still works fine.

Yes, detected this while working on my project. I expect to add a fix during this week 👍

@sriharikapu I added a fix for the account checkbox in approve method, hope it works for you!

Trying to use this branch in a project using yarn 2 which is not compatible with node >=10.12 and node < 11. Curious on why this can only be used with those versions of node.
