inspec outputs full hash when testing ini style file option with [header]

[shoekstra]

Description

When testing config in a mysql conf file with a [mysqld] header using the mysql_conf resource, the entire hash is returned in the test result instead of just the config option being tested. This could affect other INI style files too.

Instead of seeing:

  {"log_bin"=>"/var/log/mysql/mariadb-bin", "sync_binlog"=>"0"}
     ✔  ["sync_binlog"] should eq "0"

I would expect to see this (as you would without the ini style section header):

  MySQL Configuration
     ✔  sync_binlog should eq nil

InSpec and Platform Version

inspec 1.16.1 on CentOS Linux release 7.3.1611 (Core)

Replication Case

Create a test file (I used /tmp/my.cnf):

[mysqld]
log_bin = /var/log/mysql/mariadb-bin
sync_binlog = 0

Using InSpec shell:

inspec> describe mysql_conf('/tmp/my.cnf').mysqld do its(['sync_binlog']) { should eq '0' } end

Profile: inspec-shell
Version: (not specified)

  {"log_bin"=>"/var/log/mysql/mariadb-bin", "sync_binlog"=>"0"}
     ✔  ["sync_binlog"] should eq "0"

Test Summary: 1 successful, 0 failures, 0 skipped

@shoekstra when #1544 is merged and released, to correct this issue, you'll want to access the data as such:

describe mysql_conf('/tmp/my.cnf') do
  its('mysqld.expire_logs_days') { should cmp 10 }
end

  MySQL Configuration
     ✔  mysqld.expire_logs_days should cmp == 10

We'll look at #1543 separately.
