Verify OpenZeppelin SDK Proxy Contract

@rstormsf manually verified the OpenZeppelin SDK Proxy Contract on Kovan and had to do the following.

Example Proxy contract verified with:

  • Contract Name: AdminUpgradeabilityProxy
  • Compiler Version: v0.5.3+commit.10d17f24
  • Optimization Enabled: No with 200 runs
  • Other Settings: default evmVersion, None

I want to reproduce and write up this process.
