HPCC-9034 Add Package Maps GUI to EclWatch

This fix adds Package Maps link to EclWatch navigation section. From this
link, EclWatch displays a list of all Package Maps and multiple controls
for Package Maps. The list may be filtered using target, process, etc.
The controls may be used to add new Package Maps, activate/deactivate
Package Maps, and delete Package Maps. Details of each Package Map may be
viewed using Open button.

HPCC-9034 Use Ajax call and structure array for deleting

Multiple package maps may be deleted in one service request.
The information about one package map contains multiple
items. Structure array is the best option to pass the
information. To pass it in a service request, XML data is
sent through Dojo Ajax function. The response has to be
parsed since it is in a special SOAP/XML format.

HPCC-9034 Send process in DeleteProcessMap request

For now, we only support '*' as process filter. But, we may use
other process filter in the future. So, it should be sent inside
DeleteProcessMap request.
