Governance

# Publish SNS Governance WASM Built at Commit 12afb25

__Proposer__: arshavir.ter.gabrielyan at dfinity.org

__Source code__: [12afb2543219f43e4088e1ecd6d235962e71b211][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/12afb2543219f43e4088e1ecd6d235962e71b211

## Features & Fixes

###  Added

####  New `get_metrics` function for SNS Governance

A new function, `get_metrics`, has been added to the SNS Governance canister. This allows front-end clients and SNS aggregators to query for activity metrics of an SNS over a specified time period. Currently, the metrics include the number of most-recent proposals and the timestamp of the latest SNS ledger transaction.
