Plugins reload is not propagated to the nodes in HA

When adding / editing a user plugin and running the reload API to reload it:

https://www.jfrog.com/confluence/display/RTF/Artifactory+REST+API#ArtifactoryRESTAPI-ReloadPlugins

If it is a HA setup, the reload is not propagated to the nodes in the cluster.

Steps to reproduce:

1. Add the below user plugin to the primary node:

https://raw.githubusercontent.com/jfrog/artifactory-user-plugins/master/dummyPlugin/dummyPlugin.groovy

2. After it is propagated to the node, run the reload API

https://www.jfrog.com/confluence/display/RTF/Artifactory+REST+API#ArtifactoryRESTAPI-ReloadPlugins

3. Run the below curl from the node that did not get the reload request:

curl -X POST http://localhost:8081/artifactory/api/plugins/execute/dummyPlugin

You will get the below error:

{
  "errors" : [ {
    "status" : 404,
    "message" : "No execution plugins are loaded."
  } ]
}

While you would get Okay from the node that got the reload request:

{"status":"okay"}

Workaround:

Run the reload API manually to the specific IP of EACH node in the cluster or gracefully restart all Artifactory nodes.
