* message.nim: set max message size to 150KiB according to spec
Using KiB instead of KB because that seems more aligned with
the actual default defined in nim-libp2p (1024 * 1024)
Spec details: https://rfc.vac.dev/spec/64/#message-size
* test_protocol.nim: align test to current WakuMessage limit
* test_waku_client.nim: adapt test to MaxWakuMessageSize change
* make maxMessageSize configurable for wakunode2
* wakunode2 app now accepts max-num-bytes-msg-size with KiB, KB, or B units
* testlib/wakunode.nim: set maxMessageSize: "1024 KiB"
* test_waku_client.nim: remove duplicate check in "Valid Payload Sizes"
* set DefaultMaxWakuMessageSizeStr as the only source of truth
* external_config.nim: rename max-num-bytes-msg-size -> max-msg-size
* on_chain/group_manager: use .async: (raises:[Exception]).
* bump nim-dnsdisc
* update nim-chronos to the latest state
* chat2.nim: catch any possible exception when stopping
* chat2bridge.nim: make it to compile after vendor bump
* ValidIpAddress (deprecated) -> IpAddress
* vendor/nim-libp2p additional bump
* libwaku: adapt to vendor bump
* testlib/wakunode.nim: adapt to vendor bump (ValidIpAddress -> IpAddress)
* waku_node: avoid throwing any exception from stop*(node: WakuNode)
* test_confutils_envvar.nim: ValidIpAddress -> IpAddress
* test_jsonrpc_store: capture exception
* test_rln*: handling exceptions
* adaptation to make test_rln_* to work properly
* signature enhancement of group_manager methods
