RADICAL base directory

[mtitov]

User directory for configs is set by RADICAL_CONFIG_USER_DIR env variable here (by default $HOME dir is used) and has hierarchy which is similar to what method get_radical_base (RADICAL_BASE -> get_base) produces here.

Proposal to have one approach (a single method) for a base directory to keep temporary files (cache), configs, etc.

Base directory

• client: local files and user configs
  • Follow XDG Base Directory specification
    • user-specific configs, default to $HOME/.config, e.g., $HOME/.config/radical/pilot/resource_ornl.json or $XDG_CONFIG_HOME/radical/pilot/resource_ornl.json ($XDG_CONFIG_HOME/resource_ornl.json?)
    • user-specific data, default to $HOME/.local, e.g., $HOME/.local/radical/saga/adaptors
• pilot (remote)
  • currently: RADICAL_BASE contains resource sandbox path (…/radical.pilot.sandbox)
