• Fixed issue with relative plugin paths on Linux systems when they are built

Deprecated

• Both API endoints api/service/<servicename> and api/process/<processname> will be removed in version 2.1.0 and should be replaced by api/services?service=<servicename> and api/processes?name=<processname> instead
• The API endpoint api/agent/plugin/<pluginname> will be removed in version 2.1.0 in favor of api/plugins/<pluginame> which better matches the current API node naming conventions and is a less confusing name
