Feat: Schema Validation Overhaul (#128)

## What

* Overhaul schema validation by adding `internal/schemautils` and
package
* Overhaul general utils pattern by removing `utils.go` adding
`internal/datautils.go`
* Rename and move `client` package to `codefresh.cfclient`
* Ensure plan-time CRON validation for `codefresh_pipeline` matches
current API constraints, while maintaining backwards compatibility for
the deprecated `codefresh_pipeline_cron_trigger` resource, which has
different API constraints (6 fields instead of 5)

## Why

* More DRY
* Better package structure
* CRON Validation fix
