option to launch inter protocol contracts after bootstrap

[dckc]

Instagoric currently runs the proposals to start the Inter Protocol contracts as part of chain bootstrap:

instagoric/bases/shared/entrypoint.sh

Lines 358 to 359 in e9b4172

	contents="$(jq -s '.[0] + {coreProposals:.[1]}' $source_bootstrap /tmp/formatted_proposals.json)" && echo -E "${contents}" > /usr/src/agoric-sdk/packages/vats/decentral-core-config-modified.json
	export BOOTSTRAP_CONFIG="@agoric/vats/decentral-core-config-modified.json"

In the April / May Runbook: RUN Protocol Preview, we bootstrapped the chain first and then seprately launched the contracts as a consequence of a governance vote. Agoric/agoric-sdk#5819 (comment) notes that running them separately like that is not something we do often; in particular, instagoric doesn't do it. Given that we aim to do them separately in production, instagoric should support it.

Based on the efforts completed in Agoric/agoric-sdk#6957 this is no longer necessary.
