Change shared clients destination frequently for enhanced anonymity

[DjJeshk]

At Jetty server logs address like f4nag3PbSZQhSWD1uofcXho9Jvt2Z4rpd2KtohvbliU=.i2p can be found and I see this address for some weeks (hidden search engine?).
While there is no need and way to change address for websites and other services which should be persistent, addresses which are created by shared tunnels can be used to decrease anonymity if some website owner publish their logs. Others can find out more easily what is behind certain addresses.

This gives powers to website owner, but weakens anonymity for all.

That address is actually a Routing Key, *.b32.i2p address should be put instead, if we are not writting 127.0.0.1 as address in logs.

Option already exists, enable "close tunnels on idle" and "new keys on reopen".
