Update metrics

Manually update Teku metrics for your custom dashboard.

Teku has introduced changes to metric names due to the upgrade of the Prometheus library.

Gauge names are not allowed to end with total, therefore metrics as beacon_proposers_data_total and beacon_eth1_current_period_votes_total are dropping the _total suffix

The _created timestamps are not returned by default.

Some JVM metrics have changed name to adhere to the OTEL standard (see the table below)

If you are using a custom dashboard, you must update the metric names to reflect these changes.

The following table lists the name changes for Teku metrics:

Previous Teku metric name	New Teku metric name
`beacon_proposers_data_total`	`beacon_proposers_data`
`beacon_eth1_current_period_votes_total`	`beacon_eth1_current_period_votes`
`jvm_memory_bytes_committed`	`jvm_memory_committed_bytes`
`jvm_memory_bytes_init`	`jvm_memory_init_bytes`
`jvm_memory_bytes_max`	`jvm_memory_max_bytes`
`jvm_memory_bytes_used`	`jvm_memory_used_bytes`
`jvm_memory_pool_bytes_committed`	`jvm_memory_pool_committed_bytes`
`jvm_memory_pool_bytes_init`	`jvm_memory_pool_init_bytes`
`jvm_memory_pool_bytes_max`	`jvm_memory_pool_max_bytes`
`jvm_memory_pool_bytes_used`	`jvm_memory_pool_used_bytes`
