Support ACS Commons "Managed Controlled Processes"

[ghenzler]

See https://adobe-consulting-services.github.io/acs-aem-commons/features/mcp/index.html

The API ControlledProcessManager can be used as follows to control it (groovy console example):

import com.adobe.acs.commons.mcp.ControlledProcessManager
ControlledProcessManager cpm =  getService(ControlledProcessManager.class)
def processDef = cpm.findDefinitionByNameOrPath("Asset Report")
println ("count active="+cpm.getActiveProcesses().size())
def assetsReportInstance = cpm.createManagedProcessInstance(processDef, "Asset Report by groovy")
assetsReportInstance.init(resourceResolver, [baseFolder: '/content/dam', folderLevels: 5, includeSubassets: true, includeVersions: true])
assetsReportInstance.run(resourceResolver)
println ("Started assetsReportInstance="+assetsReportInstance)
println ("count active="+cpm.getActiveProcesses().size())
println ("sleeping 3sec")
Thread.sleep(3000)
println ("count active="+cpm.getActiveProcesses().size())

It would be nice to be able to trigger a groovy script (and not a java class) that implements the mcp ProcessDefinition

We should also provide an example on how to use that together with Sling Pipes.
