Trying to implement feature when active agents moving between proxies depends on HostMetadataItem value. HostMetadataItem returns a string contains proxy name which it must be controlled and ServerActive point to all needed proxies. Autoregistrations rules defined as below:

If metadata returns 'c7-prx-01' - the host registering on c7-prx-01 proxy and if 'c7-prx-02' - moves to the corresponding one. But autoregistration procedure repeats every time then agent goes to proxy to get configuration (RefreshActiveChecks period) and I receive next email:

Host name: c7-node-01
Host IP: 172.16.1.41
Agent port: 10050
Host metadata: c7-prx-01
Action name: c7-prx-01

Host metadata stays unchanged.

Steps to reproduce:

1. Set ServerActive to multiply proxies
2. Create an autoregistration actions as above
3. Set notification to some user
4. You will receive a mail about registered agent every time it's get configuration from proxy

Expected:
Host must be registered once.
