function Reset-JS7Agent
{
<#
.SYNOPSIS
Resets a Standalone Agent to revoke current orders, workflows etc. and to initialize the Agent
 
.DESCRIPTION
This cmdlet resets a Standalone Agent. In a first step any orders, workflows and other deployable objects are revoked from the Agent.
In a second step the Agent performs a restart and initializes its journal.
In a final step the Controller reconnects to the Agent and deploys any required deployable objects.
 
It is recommended to first check the state of orders prior to resetting the Agent and to complete or to cancel any attached orders.
Consider that orders have to be re-submitted to an Agent after reset.
 
The following REST Web Service API resources are used:
 
* /agent/reset
 
.PARAMETER AgentId
Specifies the unique identifier of an Agent.
 
.PARAMETER ControllerId
Specifies the identification of the Controller for which Agents are reset.
 
.PARAMETER Force
This switch should be used with care as it kills any tasks running with an Agent, revokes any orders and workflows
from the Agent and forces the Agent to drop its journal and to restart.
 
The purpose of this switch is to seize an Agent that is assigned a different Controller or that holds
information in its journal that is no longer applicable, for example if the Agent ID should be modified.
 
.PARAMETER AuditComment
Specifies a free text that indicates the reason for the current intervention, e.g. "business requirement", "maintenance window" etc.
 
The Audit Comment is visible from the Audit Log view of the JOC Cockpit.
This parameter is not mandatory. However, the JOC Cockpit can be configured to require Audit Log comments for all interventions.
 
.PARAMETER AuditTimeSpent
Specifies the duration in minutes that the current intervention required.
 
This information is shown in the Audit Log view. It can be useful when integrated
with a ticket system that logs the time spent on interventions with JS7.
 
.PARAMETER AuditTicketLink
Specifies a URL to a ticket system that keeps track of any interventions performed for JS7.
 
This information is shown in the Audit Log view of JOC Cockpit.
It can be useful when integrated with a ticket system that logs interventions with JS7.
 
.INPUTS
This cmdlet accepts pipelined input.
 
.OUTPUTS
This cmdlet returns no output.
 
.EXAMPLE
Reset-JS7Agent -AgentId 'agent_001'
 
Resets the indicated Agent.
