TRUNK-6066 Rename host.url global property

[wikumChamith]

Description of what I changed

The host.url global property is inconsistent with usage in password reset API. This renames host.url to security.passwordResetUrl .

Issue I worked on

see https://issues.openmrs.org/browse/TRUNK-6066

I made the suggested changes proposed in the issue. BTW I am not sure from where a value gets set to OpenmrsConstants#GP_HOST_URL. Because its default value is "".

However in the test UserServiceTest#setUserActivationKey_shouldCreateUserActivationKey it is manually set to "http://localhost:8080/openmrs/admin/users/changePassword.form/{activationKey}".
