Improve capture to capture REST properties correctly

[grtjn]

If you capture the modules-db of an App Builder application, that will also capture the REST api properties directly out of the database. If you try to deploy that as is to somewhere else, Roxy will stop you saying the properties are in old format. Related to #188.

The capture should instead use the REST api to retrieve the properties in their correct format. This does require knowing the port number. That can be derived from the server name of the App Builder application. The modules-db can also be derived from that server name. The capture command would become:

ml local capture --app-builder=my-app-builder-app

Here a manual work-around as well:

<map:map xmlns:map="http://marklogic.com/xdmp/map" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <map:entry key="content-versions">
    <map:value xsi:type="xs:string">none</map:value>
  </map:entry>
  <map:entry key="validate-options">
    <map:value xsi:type="xs:boolean">true</map:value>
  </map:entry>
  <map:entry key="document-transform-out">
    <map:value xsi:type="xs:string">appidentitytransform</map:value>
  </map:entry>
  <map:entry key="debug">
    <map:value xsi:type="xs:boolean">false</map:value>
  </map:entry>
  <map:entry key="error-format">
    <map:value xsi:type="xs:string">json</map:value>
  </map:entry>
  <map:entry key="validate-queries">
    <map:value xsi:type="xs:boolean">false</map:value>
  </map:entry>
  <map:entry key="can-copy">
    <map:value xsi:type="xs:boolean">true</map:value>
  </map:entry>
</map:map>
let $map := map:map($mapxml)
return
  <properties xmlns="http://marklogic.com/rest-api">{
    for $key in map:keys($map)
    where $key != 'can-copy'
    return
      element { xs:QName($key) } { map:get($map, $key) }
  }</properties>
