Change the data type for metadata and content fields in v1alpha1.CacheSizeSettings

[kale-amruta]

Change Overview

// CacheSizeSettings are the metadata/content cache size details
// that can be used while establishing connection to the kopia repository
type CacheSizeSettings struct {
	Metadata string `json:"metadata"`
	Content  string `json:"content"`
}

Currently the Metadata and Content fields in CacheSizeSettings have string as a data type whereas kopia CLI accepts the values for these fields as integer.

It would be better if the CRD accepts the fields in Integer format since that would reduce the number of conversions required in the GO code

This PR changes the field types to *int for metadata and content fields
