Separate binary that creates/validates Spindle config files. Work in progress.

[rountree]

spindle-config-helper is built using the same config_mgr.cc as Spindle and will pull in and parse runtime parameters from the same sources, including the command line.

The design philosophy is to validate those runtime parameters, issue warnings and validation where needed, and then dump all parameters and their current values to stdout. The user can redirect the output to their spindle.conf file.

Here's a snapshot of current functionality:

# Security configuration:
#   Current mode: munge
#     Munge authentication enabled
#
#   Munge availability:
#     Munge is available and working (recommended security option)
#
# Spindle filesystem recommendations:
#   Local: /dev/shm (tmpfs, 250GB), /tmp (tmpfs, 428GB)
#
#   commpaths analysis:
#     WARNING: /bad_commpath -> /bad_commpath
#       Path does not exist (will be created by Spindle)
#       Parent directory (/) is not writable
#     OK: /tmp/commpath -> /tmp/commpath (tmpfs, 428GB)
#
#   cachepaths analysis:
#     WARNING: /bad_cachepath -> /bad_cachepath
#       Path does not exist (will be created by Spindle)
#       Parent directory (/) is not writable
#     OK: /tmp/commpath/cachepath -> /tmp/commpath/cachepath (tmpfs, 428GB)
#
#   pythonprefix analysis:

#       Path does not exist
#     WARNING: /usr/lib64/python -> /usr/lib64/python
#       Path does not exist
#
#   localprefix analysis:
#     WARNING: /var/ -> /var
#       Cannot determine filesystem type
#     OK: /tmp/ -> /tmp (tmpfs, 428GB)
#     OK: /proc/ -> /proc
#     OK: /dev/ -> /dev
#     OK: /sys/ -> /sys
