v2.0.1 - Block production and more

Block production metrics

solana_exporter is now tracking the number of skipped and produced blocks via the solana_leader_slots_total metric. This re-implements the solana block-production CLI call, but per slot rather than windowed per epoch:

slots.go:116] confirmed slot 56689556 (offset 5300, +8), epoch 144 (from slot 56684256 to 57116256, 426700 remaining)
slots.go:133] confirmed blocks: 56689548 -> 56689555: [56689548 56689549 56689550 56689551]

New chain state metrics

In addition to block production, the following metrics were added:

• solana_confirmed_epoch_first_slot - Current epoch's first slot.
• solana_confirmed_epoch_last_slot - Current epoch's last slot.
• solana_confirmed_epoch_number - Current epoch.
• solana_confirmed_slot_height - Last confirmed slot height observed.
• solana_confirmed_transactions_total - Total number of transactions processed since genesis.

Node pubkey

In addition to the pubkey field for the vote key, solana_validator_* metrics now include a nodekey label, which is the validator's identity pubkey. The pubkey field is not renamed for backwards compatibility reasons.

Flags for configuration (BREAKING)

We're now using flags instead of environment variables (see README).
