Matthew Oliver 090baa1fa9 Swift configuration parameter audit 
This change is the result of an audit through the config parameters
provided by swift and how/if they are addressed in the swift
documentation. The documentation being the sample config files in
the /etc directory or the documentation.
This change is only concerned with the config files in etc/ next
I will look at the documentation in the doc/ folder.
This change makes the following assumptions:
 - Unless stated otherwise, the commented out parameter in the
 sample configuration is the default for swift.
 - When the default in the code differs from that of the sample
 configuration, the default in the code is correct.
Container reconciler:
 Parameter: interval
 - code: 30
 - config: 300
 Result: config = 30
Object Expirer:
 Parameter: recon_cache_path
 - code: /var/cache/swift
 - config: Parameter missing
 Result: Add parameter
swift-dispersion-populate && swift-dispersion-report
 Parameter: auth_version
 - code: 1.0
 - config: 2.0 (due to being a confusing example of how to setup
 version 2.0).
 Result: Added 'auth_version = 1.0' to the right section (showing
 default and make the sample configuration for auth version
 2.0 easier to understand.
swift-drive-audit:
 Parameter: log_file_pattern
 - code: /var/log/kern.*[!.][!g][!z]
 - config: /var/log/kern*
 Result: config = /var/log/kern.*[!.][!g][!z]
 NOTE: swift-drive-audit uses a parameter called device_dir which
 defaults to '/srv/node'. In all other swift binaries/services
 there is a similar parameter called devices which stores the
 same thing. This is an inconsistency which I haven't fixed
 as this could break existing swift clusters out in the wild.
Proxy Server:
 Parameter: object_chunk_size
 - code: 65536
 - config: 8192
 Result: config = 65536
 Parameter: client_chunk_size
 - code: 65536
 - config: 8192
 Result: config = 65536
 Parameter: strict_cors_mode
 - code: True
 - config: No parameter
 Result: config = True
Account and Container replicator configuration confusion:
 NOTES:
 The account and container replicators have parameters:
 - interval
 - run_pause
 Both of these are loaded into the same variable in code:
 self.interval = int(conf.get('interval') or
 conf.get('run_pause') or 30)
 If a user sets both to different values then interval is used.
 Result: Update the configuration to make this more clear.

# device_dir = /srv/node
# log_facility = LOG_LOCAL0
# log_level = INFO
# log_address = /dev/log
# The following caps the length of log lines to the value given; no limit if
# set to 0, the default.
# log_max_line_length = 0
# minutes = 60
# error_limit = 1
#
# Location of the log file with globbing
# pattern to check against device errors.
# log_file_pattern = /var/log/kern.*[!.][!g][!z]
#
# Regular expression patterns to be used to locate
# device blocks with errors in the log file. Currently
# the default ones are as follows:
# \berror\b.*\b(sd[a-z]{1,2}\d?)\b
# \b(sd[a-z]{1,2}\d?)\b.*\berror\b
# One can overwrite the default ones by providing
# new expressions using the format below:
# Format: regex_pattern_X = regex_expression
# Example:
# regex_pattern_1 = \berror\b.*\b(dm-[0-9]{1,2}\d?)\b
