Remove deprecated fields from storagecluster & ocsinitialization types

[malayparida2000]

These fields have been lying around without usage since very long, we should now get rid of them.

[malayparida2000]

Just for reference if we were using any of these removed fields anywhere in our code, Our code would not have compiled & would have faced CI failures.

We should probably move the NewToolsDeployment from storagecluster types to cephtoolbox.go
