Implement missing-blocks-guardian and include it into deb pkg

[smorci]

Explain your changes:

• Add missing-blocks-guardian script which is inspired from download-missing-blocks
• Copy script to archive debian package

Explain how you tested your changes:

• local test on a healthy mainnet archive database hosted on AWS by MF
• I am interested in testing it on a broken database
• I am interested in testing it from the debian package

Checklist:

• Dependency versions are unchanged
  • Notify Velocity team if dependencies must change in CI
• Modified the current draft of release notes with details on what is completed or incomplete within this project
• Document code purpose, how to use it
  • Mention expected invariants, implicit constraints
• Tests were added for the new behavior
  • Document test purpose, significance of failures
  • Test names should reflect their purpose
• All tests pass (CI will check this if you didn't)
• Test on broken DB
• Test from debian package

The script should always report some meaningful message be that usage, error or just info. If other behavior is noticed, please notify me.

@emberian I included you because this will be included in the maintenance replayer package once it is done.

@dkijania could you help me come up with an idea to test it on a broken DB?

@smorci in order to test script against broken database I propose you to utilize archive-block app and devnet or mainnet precomputed blocks. scenario would look like below:

1. Create empty mainnet database with schema only
2. Using gsutil download precomputed blocks from o1labs bucket (mina_network_block_data) with prefix devnet or mainnet. You can skip some height (precomputed blocks name format is {network-height-state-hash.json} so you can easily avoid particular heights in order to prepare broken db
3. Using archive block app import into database downloaded precomputed blocks
4. Run guardian

I've tested script using mainnet network . Looking good

@smorci I think we can remove src/app/rosetta/download-missing-blocks.sh script which duplicates script you just developed
