feat: runtime chain-hash, chain-id and chain-name

[vmmon]

Description

Summary of the changes...

• I have updated CHANGELOG.md with a new entry if my PR makes any breaking changes or fixes a bug. If my PR removes a feature or changes its behavior, I provide help for users on how to migrate to the new behavior.
• I have carefully reviewed all my Cargo.toml changes before opening the PRs. (Are all new dependencies necessary? Is any module dependency leaked into the full-node (hint: it shouldn't)?)

Linked Issues

• Fixes # (issue, if applicable)
• Related to # (issue)

Patching the binary on Linux is straightforward with objdump --dump-section and a objdump --update-section.

Patching the binary on MacOS can be done with:

#!/bin/sh

set -e
FILE=$1
OFFSET=$(otool -l $FILE | grep __CONSTANTS -A 5 | grep offset | cut -c 12-)
SIZE=$(otool -l $FILE | grep __CONSTANTS -A 5 | grep size | cut -c 12-)


TMPFILE=$(mktemp)
dd of=$TMPFILE if=$FILE bs=1 skip=$OFFSET count=$SIZE status=none
vi $TMPFILE
dd if=$TMPFILE of=$FILE bs=1 conv=notrunc seek=$OFFSET count=$SIZE status=none
codesign --remove-signature $FILE
codesign -s - $FILE
