[BUG] Plugin rule update did not take effect in time.

Bug Description

After the plug-in matching rule is updated, the new rule of the request gateway does not take effect.

synchronous invalid.

Context

After I modified the rule in shenyu admin, the synchronization gateway was triggered, and the gateway did not seem to handle it correctly

The gateway uses prefix tree to store rules, and the processing logic of updating action is putNode, so the historical rules are not cleaned up, which leads to the request interface still using the old rules after updating rules

Divide plugin, the source address can still be accessed after the Condition changes, which is fatal:

Similarly, WAF plugin
After the firewall rule switch changes, it does not take effect, which is also fatal:

Direct request after configuration--> Success

Synchronize and request again after configuration--> Success

Every time a rule is saved, there is an additional rule cache, and the historical enable=true rule is also in it. The result is that the match is not matched according to the new rule.

This could be a BUG, I used the jmeter test and inserted 240,000 rule caches, which could lead to OOM?
