Loadbalancer (relayd): renaming pool does not rename them in virtual servers

[adam65535]

If you rename a pool the virtual servers that specify the pool do not get updated to the new name.  When you save changes relayd shows 'configuration reloading FAILED'.

If you only have a few loadbalancer entries it probably is easy to remember to change the virtual servers too but when you have a few pages of loadbalancer entries you (I) might miss some :).  It would be great if you rename a pool that the names get changed in the virtual server tab too where they are used in existing virtual server entries.

Tested on the following and the same behavior experienced:
