This commit refactors the `ChartBuilder` that used to be a do-it-all
struct into an interace with two implementations:
- `LocalChartBuilder`: to build charts from a source on the local
filesystem, either from a directory or from a packaged chart.
- `RemoteChartBuilder`: to build charts from a remote Helm repository
index.
The new logic within the builders validates the size of the Helm size
it works with based on the `Max*Size` global variables in the internal
`helm` package, to address the recommendation from the security audit.
In addition, changes `ClientOptionsFromSecret` takes now a directory
argument which temporary files are placed in, making it easier to
perform a garbage collection of the whole directory at the end of a
reconcile run.
