This fixes the file_concat dependency issue postgresql module has brought in,
plus removes some deprecation warnings from our rspec tests.

I've also bumped rspec-puppet as well, while I was at it.

(maint) Add file_concat and bump rspec versions

command-processing section.

Added new class server/config_ini.pp to manage contents of the config.ini.
Three new parameters added:
  * command_threads
  * store_usage
  * temp_usage

All three default to 'undef'. This makes sure (potential) custom settings
done to that file with regard to above three variables are 'absent',
and let PuppetDB built-in defaults take care.

Documentation to the README.md added, as well as unit tests.

My use-case was, that I have on some nodes a too small /var partition,
so I had to lower the values of store-usage and temp-usage in the config.ini
manually.

Enable the module to manage entries in $confdir/config.ini

This fixes the ordering for the read_database_ini class, and fixes a small
notification problem with config_ini as well.

validation resource.

(maint) Allow database_validation to be false

This provides an override mechanism for providing a custom path to HSQLDB.

This allows users to provide any path to their HSQLDB database. It is needed
specifically for managing the as-yet-unreleased version of PuppetDB as well.

Previously we were packaging the Rakefile & Gemfiles, however this is unnecessary.
