decouple the subcharts from the main chart

[bramaq]

As the project grows the chances are the charts for each component might need to evolve individually. If instead of forcing the "subcharts" pattern they are managed/versioned as individual charts it would facilitate release cycles, integration into cd tools (ie as individual argocd apps) while you can still keep a main chart that has the others as dependencies if desired.

started work on this... Have a quick question about versions, should keep the first version of spire-agent, etc... as 0.1.0 or should I make then match 0.6.3 ?

Probably match the 0.6.3 version? Its probably more reflective of the state of the chart then 0.1.0.
