Do not cast using NGSIv2 types in updateAction (version 2)

[AlvaroVega]

Currently there are some automatic cast about types:

• Number
• Text
• Booleam
• None
• DateTime

What do we want?
Currently updateAction in version 2 is trying to cast (after expandVars) to NGSIv2 types like:

var changes = {};
    action.parameters.attributes.forEach(function(attr) {
        // Direct value for Text, DateTime, and others. Apply expandVar for strings
        let theValue = myutils.expandVar(attr.value, event, true);
        let theType = myutils.expandVar(attr.type, event);
        // Metadata should be null or object
        let theMeta = attr.metadata;
        var date;
        switch (theType) {
             case 'Text':
                 theValue = theValue.toString();
                 break;
             case 'Number':
                 theValue = parseFloat(theValue);
                 break;
             case 'Boolean':
                 if (typeof theValue === 'string') {
                     theValue = theValue.toLowerCase().trim() === 'true';
                 }
                 break;
             case 'DateTime':
                 if (parseInt(theValue).toString() === theValue) {
                     // Parse String with number (timestamp__ts in Perseo events)
                     theValue = parseInt(theValue);
                 }
                 date = new Date(theValue);
                 theValue = isNaN(date.getTime()) ? theValue : date.toISOString();
                 break;
             case 'None':
                 theValue = null;
                 break;
         }
        var key = myutils.expandVar(attr.name, event);
        changes[key] = {
            value: theValue,
            type: theType
        };

@fgalan Which version is used by default (v1 or v2) for that notification?

[AlvaroVega]

@fgalan Maybe we can add a configuration flag option (and env var) to enable or disable it, instead of remove all ? It would be disabled by default
