fab - configurable options

[hossbeast]

fab needs a system for user-configurable options, similar to git. i.e. you have an options-file, ~/.fabrc, and then options can be overridden on the cmdline.

This is different from options that are meaningful for how the build is calculated/executed. For example, I am also planning options(s) for how to detect source file changes (stathash, contenthash, inotify, etc) but those should be specified in the fabfile(s) themselves.

options

• default logger tags
• amount to copy from stderr when a cmd fails
• whether to include stdout when a cmd fails
• whether to include the cmd when a cmd fails
• node identification in log messages (relative to cwd, relative to inif-fabfile-dir, absolute, canonical)
• cycle reporting mode (fail (default), warn, ignore)
• backtrace mode (only applies to debug/devel build)

Config parsing / reloading / subsystem reconfiguration has now been implemented.

I'll keep this open until I can include some documentation on the file format, where the files go, how precedence works, and implement some of the options mentioned.

Right now, the options implemented are:

• logging.console.exprs
• filesystem
• extern
