Makes a few changes to `pd`, designed to improve peering behavior on testnets: * raises the default values for inbound/outbound peers * limits the number of peers discovered during join to 5, randomized We originally decided to add node discovery logic to aid in peering. There's a downside, however, to reusing all peers of the bootstrap node: the CI deployment nodes get swamped, and the network remains centralized on the nodes that Penumbra Labs run. Instead, let's just take a handful, at random, and trust the p2p gossip to discover more over time. Refs #3056.

When joining a network via `pd testnet join`, pd already inspects the peers known to the target bootstrap node, and includes those peers in the generated CometBFT config. Technically it's not correct to assume that these peers are seeds, but limiting to a threshold (#3063) ensures that only a few nodes will be miscategorized this way. The new behavior introduced here is that `pd testnet join` will inspect monikers of peers learned from the bootstrap node, and if the string "seed" appears in the moniker, guarantee that peer lands in the `seeds` field of the CometBFT config. To complement this change, we update the deployment logic to create a seed node, and ensure that seed node is excluded from the loadbalanced RPC, to avoid hitting it via the join request (in which case it won't report many peers, because seed nodes drop peer connections after serving address info). Refs #3056.
