feat: Sealevel RPC failure / success metrics and alerts

[kamiyaa]

Description

• Add sealevel metrics

I moved a bunch of RPC and provider initantiation logic into chains.rs instead of spread across multiple different structs. ie. SealevelInterchainGasPaymasterIndexer, SealevelInterchainGasPaymaster, SealevelInterchainSecurityModule, etc.
I think this makes it more flexible for changes moving forward.

• Copied most of HttpSender code from Solana's codebase: https://github.com/anza-xyz/agave/blob/ddec7bdbcf308a853d464f865ae4962acbc2b9cd/rpc-client/src/http_sender.rs#L132
  • This is because this struct is private so we can't just wrap a struct around it.
• PrometheusSealevelRpcSender wraps around this new HttpSender and then implements Solana's RpcSender
  • This then gets used when creating solana's RpcClient to work with everything else while also providing metrics

Drive-by changes

• add some builders to certain structs
