MgmtConverter is called from doRemap

[masaori335]

Some overridable configs are running special MgmtConverter when ATS does remap. It'd be great if they're converted when configs are loaded.

• e.g. HttpTransact::HOST_RES_CONV for proxy.config.hostdb.ip_resolve

In the OverridableHttpConfigParams, below config params are running special converters. And I'm trying to add two more for negative_caching_list and negative_revalidating_list.

HttpForwarded::OptionBitSet insert_forwarded;
ts_seconds down_server_timeout{300};
ConnectionTracker::TxnConfig connection_tracker_config;
HostResData host_res_data;

(for ts_seconds, it's just a static_cast, so it's not problem.)
