* Update cost model to use requested_cu instead of estimated cu #27608
* remove CostUpdate and CostModel from replay/tvu
* revive cost update service to send cost tracker stats
* CostModel is now static
* remove unused package

PR #28317 previously attempted to fix a case where blockstore processing
would create children banks for slots past the halt_at_slot.
However, the previous fix didn't handle the case where a slot could be
strictly less than the halt_at_slot, but have children that were greater
than the halt_at_slot. For example, this could happen if a child of slot
S is S+n where n > 1.
Thus, this change covers our processing logic to cover this second case
as well.
load_frozen_forks() finds new slots to process by creating new Banks for
the children of the current slot in process_next_slots(). Prior to this
change, we would then immediately check if we had reached the
halt_at_slot and correctly halt processing when appropriate. As such, it
would be possible for Banks to be created for slots beyond the
halt_at_slot.
While a potential child slot that is past halt_at_slot wouldn't be
replayed, the Bank being created still alters some universal state in
AccountsDb. So, this change moves the halt_at_slot check before we
create children Banks in process_next_slots().
Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case

#### Problem
blockstore_db.rs has a mutual dependency between blockstore_metrics.rs.
#### Summary of Changes
This PR removes the mutual dependency by moving the option-related stuff
out from blockstore_db.rs to its new home --- blockstore_options.rs.
By doing this, we address the mutual dependency and also make the code cleaner.
