Description

in Kubo RPC client, there was a minor discussion in a PR to have the client API match the RPC endpoints, but that some of the endpoints should be removed and instead be passed as parameters (similar to CLI):

• https://docs.ipfs.tech/reference/kubo/rpc/#api-v0-bitswap-wantlist should allow passing peer to wantlist
• https://docs.ipfs.tech/reference/kubo/rpc/#api-v0-bootstrap-add-default should just be /add with a default flag.
• https://docs.ipfs.tech/reference/kubo/rpc/#api-v0-bootstrap-rm-all should be /bootstrap/rm with an all option
