feat: add support for slashing parameters and missed blocks per signing window

[qwertzlbert]

This pull request introduces a new set of features for exporting network slashing parameters to Prometheus, along with additional metrics to monitor validator performance and slashing conditions.

Key Changes
Prometheus Metrics for Slashing Parameters:

Exports key network slashing parameters, such as the Signing Window size and Slashing Penalties to Prometheus.
Validator “Missed Blocks per Signing Window” Tracking:

Adds the ability to query the current count of "Missed Blocks per Signing Window" for each validator. This metric aligns with the network’s threshold for determining whether a validator should be jailed.
Optional Slashing Metrics Collection:

Users can disable the collection of slashing-related metrics by using the --no-slashing argument.
Consensus Address Matching for Validator Metrics:

The validator's public key (PubKey) and the network's detected human-readable prefix are used to derive the consensus address. This enables proper mapping of metrics returned from the SigningInfo module, which provides metrics in the Bech32 Consensus Address format.

Testing and Validation
This change has been tested across several networks, ensuring compatibility and accurate metric collection:

Networks Tested:

• Axelar
• Cosmos
• Band
• Osmosis
• Injective
• Zeta
• Agoric

Additionally a unit tests have been added and updated.

Additional Notes

These additions will enhance monitoring and alerting capabilities for validator operators by providing real-time insights into slashing parameters and validator performance. This feature set will improve operational awareness, helping operators avoid slashing events.

@MattKetmo thanks for your quick and extensive review! I'll add the suggested changes as soon as possible.

[qwertzlbert]

@MattKetmo I addressed your comments and added your suggestions and required changes. Feel free to take another look whenever you have time.
I did not deploy the changes to my test environment yet however, so please let me check this in a more "productive" setting before merging
