Missing spring-security-oauth2 xsds after release

[sjohnr]

Describe the bug

The following schema files are not deployed with each release:

• http://www.springframework.org/schema/security/spring-security-oauth-1.0.xsd
• http://www.springframework.org/schema/security/spring-security-oauth2-1.0.xsd
• http://www.springframework.org/schema/security/spring-security-oauth2-2.0.xsd

Expected behavior

Since legacy spring-security-oauth2 based applications using the "http" scheme rely on these schema files, they should be published with each Spring Security release.
