engine: Replacing getVds() query by getVdsStatic() query in VDSCommands

The following patch will replace a getVds() query by getVdsStatic() query in almost all vds (not spm) commands.
THe reasons are:
1. A getVds() query - is a query to view, which is based on JOIN from at least 7 tables, getVdsStatic() it is a query
to single table, meaning much more faster.
2. VDSStatic object is smaller than VDS object, less resources spent on retrievening it from DB, allocatin memory, etc...
3. VDSStatic object almost never changed, it is means that when it will be cached, we will not perfrom any query during
vds commands, the VDS object contains VDSDynamic part, which is changed very frequently, so caching of VDS object is more
difficult and possible not efficient.
4. No reason to use VDS object , when we can use VDSStatic object

Also patch includes a following fixes and improvements:
1. FullListVDSCommand will never perform a query to vds object, it will be passed via parameters
2. A part of code moved from GetCapabilitiesVDSCommand to CollectVdsNetworkDataVDSCommand, this code is not relevant
   for GetCapabilitiesVDSCommand and only relevant for CollectVdsNetworkDataVDSCommand
3. Code clean up

Also, after applying a patch, a query for VDSStatic will be made only if it is required to log command, and not always in
constractor

engine: Removing date creation from MultipleActionsRunner during logging

Removed explicity date creation during logging in MultipleActionsRunner.
Logger is writting date, so no reason to write by myself

engine: Fixing correlationId in MultipleActionRunner

The following patch should connect canDoAction with execute part of command by correlationId.
From now, all loggs related to command which was run via MultipleactionRunner will have same correlationId.
Removed some code which is checking if command has correlationId as irrelavant
