Support configuration of chartPathOptions in install/upgrade client interfaces

[vl306]

The existing helm install/upgrade client interface functions doesn't seem to support configuration of the chartPathOptions. We have a use case where we want to set "client.ChartPathOptions.InsecureSkipTLSverify = true".

One option is to modify the functions to take the additional argument.

If this the right/preferred approach?.

Existing Client interface:

 InstallOrUpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)
 InstallChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)
 UpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)

Proposed Changes:

  InstallOrUpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions, chartPathOptions *action.ChartPathOptions) (*release.Release, error)
  InstallChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions, chartPathOptions *action.ChartPathOptions) (*release.Release, error)
  UpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions, chartPathOptions *action.ChartPathOptions) (*release.Release, error)

Alternatively, to avoid changing the interface, the ChartPathOptions can be added to GenericHelmOptions:

 }

Agreed, and yes please.

My case is not about skipping TLS verification, albeit related. Instead of disabling verification I wish to provide the necessary supporting certificates through the ChartPathOptions.CaFile field.
