Implement rate-limits

Due to certain recent events, rate-limits are clearly missing from the streaming lib.
Option for limiting concurrent connections would be: i2p.streaming.limit.concurrentStreams

Proposal for ratelimiting:

Don't look at concurrent connections alone, but make it a real limiter
with a defined limit for connections/minute,hour,day from the same

The values for could be part of the extended configuration options

….. .servertunnelx.useRateLimiter=true
….. .servertunnelx.RateLimits?=½/10

if the ratelimit hits the offending client should be held for a random amount
of seconds (up to 15) and then be treated like the service is not active/reachable.
Sorry for not using the right lingo…

Even better, do this as an I2CP option, so that applications can have access to the feature.

Maybe, maybe not. Is connection rate limiting "clearly" a feature for the streaming lib and not something to be solved at the application level? Depending on how it's done it could be fairly complex and resource-intensive too.

As a crude alternative I've implemented blocking by dest hash. Details at http://zzz.i2p/topics/614

One problem with any connection option is you can't change them on-the-fly, so you have to stop and restart the tunnel to take effect. This goes for the blocking option too.
