Non-relay, request-response protocol DOS protection configuration

Name	Default Value	Description
rate-limit		This is a repeatable option. Each can describe a specific rate limit configuration for a particular protocol. Formatted as:<protocol>:volume/period<time-unit> - if protocol is not given, settings will be taken as default for un-set protocols. Ex: 80/2s -Supported protocols are: lightpush|filter|px|store|storev2|storev3 -volume must be an integer value, representing number of requests over the period of time allowed. -period<time-unit> must be an integer with defined unit as one of h|m|s|ms - storev2 and storev3 takes precedence over store which can easy set both store protocols at once. - In case of multiple set of the same protocol limit, last one will take place. - if config is not set, - which is the default - means unlimited requests are allowed. -filter has a bit different approach. It has a default setting applied if not overridden. Rate limit setting for filter will be applied per subscriber-peers, not globally - it must be considered when changing the setting. Examples: --rate-limit="100/1s" - default for all protocols if not set otherwise. --rate-limit="lightpush:0/0s" - lightpush protocol will not be rate-limited. --rate-limit="store:130/1500ms" - both store-v3 and store-v2 will apply 130 request per each 1500ms separately. --rate-limit="px:10/1h" PeerExchange will serve only 10 requests every hour. --rate-limit="filter:8/5m" - will allow 8 subs/unsubs/ping requests for each subscriber within every 5 min.
