Typos in configuration.rst

[Samuel de Medeiros Queiroz]

doc/source/configuration.rst contains some typos that need to be fixed:

- "Keystone" is spelled as "keystone";
- Other general typos, such as:
  - "regeneratable" should be "regenerable";
  - "If the plugin require addition configurations" should be "If the plugin requires additional configurations";
  - "it's", where it should be the possessive pronoun "its".

Change abandoned by Samuel de Medeiros Queiroz (<email address hidden>) on branch: master
Review: https://review.openstack.org/146257
Reason: Abandoned since what this patch proposes is not correct.
We have to rename Keystone -> keystone, rather than the reverse.

we need a bug/patch to correct Keystone -> keystone on all our documentation.
