Unified Rucio Helm Charts

[lobis]

Usually the rucio charts are used together, so it makes sense to have a single chart that ties all the charts together.

There were some offline discussions with @labkode @bari12 and @volodymyrss and others regarding this. At the time of creating this issue there was an existing PR #217 with a similar goal.

After some discussion we propose to refactor the charts to have single rucio chart without any chart dependencies, so charts such as daemons, ui, etc. would disappear. This pattern is common among popular charts and components can be toggled via some flag, for example:

rucio:
  global:
    database: ...
  server: # enabled by default
  ui:
    enabled: true
