Build out the charts/ directory from the Chart.lock file.

Build is used to reconstruct a chart's dependencies to the state specified in

the lock file. This will not re-negotiate dependencies, as 'helm dependency update'
|
|
does.
|
|
|
|
If no lock file is found, 'helm dependency build' will mirror the behavior
|
|
of 'helm dependency update'.
