feat: add zoe upgrade to upgrade.go

[Chris-Hibbert]

refs: #10267

Description

Upgrade Zoe as part of the next software upgrade.

Security Considerations

The new Zoe will add the ability to terminate vats from bootstrap space.

Scaling Considerations

Terminating vats will allow us to address some space leakage issues.

Documentation Considerations

The new behavior is accessible on a facet that is only exposed to the bootstrap space. Doesn't need to impact developer docs.

Testing Considerations

Tested in a bootstrap test.

Upgrade Considerations

We expect to include this change with the next software upgrade, so we can start making use of the ability to remove unneeded vats.

Looks good, provided the incarnation number test is OK.

I was going to suggest an incarnation number test, but it looks like we already have one:

agoric-sdk/a3p-integration/proposals/n:upgrade-next/initial.test.js

Line 12 in 735a449

zoe: { incarnation: 2 },

It seems likely that this will fail in ci and need updating. But in any case, it's there.

I'll add force:integration to ensure I'm not breaking it.

Yep:

  Difference (- actual, + expected):

    {
    ....
      zoe: {
  -     incarnation: 3,
  +     incarnation: 2,
      },
    }
