graphman: Add chain rewind subcommand

[encalypto]

This rewinds all subgraphs on a chain to a specified block. It has most of the same arguments as graphman rewind, but takes a chain name instead of a list of deployments.

Remaining work:

• [ ] Clear block cache up to target block
• [ ] Clear call cache up to target block
