Use mixed data types in hash values

[senalkularatne]

plugin parameter definition

config_param :my_hash, :hash, :default => {}, :symbolize_keys => true

configuration file

my_hash key1:100, key2:200, key3:"hello" 

If I log @my_hash we see that it shows up as :key1 => "100", :key2 => "200", :key3: "hello" where all values are turned into strings. How can we read them as they appear, i.e. :key1 => 100, :key2 => 200, :key3: "hello"?
