[Tooling][Savepoints/Rollbacks] Implement CLI commands for Snapshots/Rollbacks

[deblasis]

Objective

Implement the commands that will target the RPC endpoints defined in #565

Origin Document

#493 and #562

Goals

Listing Available Savepoints

p1 persistence savepoints list

It would return a list of available savepoints along with some metadata including but not limited to:

• Block number
• Timestamp of snapshot creation
• Snapshot size (human-readable)
• Snapshot hash
• [Optional] Signer & signature of the snapshot

Creatin New Savepoints

p1 persistence savepoints create

It would trigger the creation of a savepoint and return the identifier/full_path & metadata for easy download

• Rollback to a previous savepoint ([PERSISTENCE] SavePoints and Rollbacks design document (Issue #493) #533 (comment))

p1 persistence savepoint rollback [snapshot hash]

Querying Savepoint Status

• Query/poll for status of an operation
  This is something that the CLI should be capable of doing as part of the Rollback command. Example:
  1. Start rollback
  2. Poll status until OK or KO
  3. Return to prompt

Deliverable

• A PR with implementation tending to the goals above
• Documentation showing an e2e flow that creates, applies and benchmarks savepoints

Non-goals / Non-deliverables

• Changes in the persistence module

General issue deliverables

• Update the appropriate CHANGELOG(s)
• Update any relevant local/global README(s)
• Update relevant source code tree explanations
• Add or update any relevant or supporting mermaid diagrams

Testing Methodology

• All tests: make test_all
• LocalNet: verify a LocalNet is still functioning correctly by following the instructions at docs/development/README.md
