Expose the ability to create Cloud Logs policies in Observability DA

[ocofaigh]

Support was added in https://github.com/terraform-ibm-modules/terraform-ibm-observability-instances/releases/tag/v3.2.0 and now needs to be exposed in the DA.

TBC:

• Are we OK to just expose the full complex variable? Is it too complex for a DA? Or maybe its OK to just add a supporting markdown doc? Should it have any default values perhaps using best practises? Something around the TCO Optimizer perhaps?

Discussed this point in Cloud Logs office hours - if there is recommendation for default policy...

Initially they said, make it 100% for Analyze and Alert as default but later they suggested for debug also.
There is no slider for %, it is by rules you have to set.

So as such no recommendation. Team also mentioned that they will up come up with some public doc in some time for app users help. Once this doc is available, then we can link it in our read me.

So I am planning to expose the full complex variable and supporting markdown doc.

@ocofaigh Let me know if you have a different opinion. Thanks.

One more point, if we set default policy and then user adds one on the top of that and if incase, it clashes with default one then first one(default one) will take priority. So user has to delete one and add another.
Hence having a default one will become overhead.

So after our discussion internally, we decided to expose the full complex input type, and create a helper doc.
