Implement upgradeability (#151)

* Implement contract upgrade VAA action

* naming and (╯°□°)╯︵ ┻━┻

* Carefully unflip table and replace broken cutlery ┬─┬ノ( ◕◡◕ ノ)

* fix and automate upgradeability

* document contract upgrade call

* Update comments

* Exhaustiveness check in VAA payload switch

* Fix typo
