DhcpServerExclusionRange: change exclusion range fails

[markatdxb]

Details of the scenario you tried and the problem that is occurring

Basically i tested to create new exclusion range which works ok
Running the same configuration also works fine as expected - idempotency is ok

Problem is when I change the parameter of the exclusion range, i get fatal error of the module
Seems that module is not able to deal with this scenario

Then i thought OK lets delete all ranges from the range and re-run the code with new parameters
Here i bumped into another issue.
This module requires Start and End IP which makes sense.
Problem is that i dont have a way to get information about existing ranges from any DSC module. That means i have create extra code to grab the exclusions and feed it to the module with parameter absent
Would be great to NOT have Start and End IP mandatory when ABSENT is selected. That way the module simply delete all Exclusion ranges

Verbose logs showing the problem

Suggested solution to the issue

I know its bit tricky issue with changing the exclusion, maybe you have some idea how to enhance it ?
