    Removed unused code from com.cloud.api.ApiServer

    **Removed “\_” from variables names**: private variables with “\_” at the beginning is common in C++ but not in Java.
     
    **Removed unused methods from ApiServer:**
    -  com.cloud.api.ApiServer.setPluggableServices(List\<PluggableService\>): this method can be removed and replaced by the annotation @Inject in the variable pluggableServices; 
    - com.cloud.api.ApiServer.getPluggableServices(): unused method;
    - com.cloud.api.ApiServer.setApiAccessCheckers(List\<APIChecker\>): can be replaced by the @Inject in the variable apiAccessCheckers;
    - com.cloud.api.ApiServer.getApiAccessCheckers(): unused method.
     
    **Methods and variables access level reviewed:**
    - com.cloud.api.ApiServer.handleAsyncJobPublishEvent(String, String ,Object): this method was private but the annotation @MessageHandler requests public methods, as can be seen in org.apache.cloudstack.framework.messagebus.MessageDispatcher.buildHandlerMethodCache(Class\<?\>), which searches methods with the @MessageHandler annotation and changes
    it to be accessible (“setAccessible(true)”). Thus, there is no reason for handleAsyncJobPublishEvent be a private method and lead some other dev to wrong conclusions about the use of the method; 
    - Global variables and methods called just by this class (ApiServer) were changed to private.
     
    **Changed variables and methods from static to non-static (if possible):** as some variables/methods are used just by one object of this class, instantiated by Spring, they were changed to non-static.
     
    With that, calls from com.cloud.api.ApiServlet.ApiServlet() that used static methods from ApiServer, were changed from ApiServer.\<staticMethodName\> to \_apiServer.\<methodName\> that refers to the org.apache.cloudstack.api.ApiServerService interface. Thus, methods com.cloud.api.ApiServer.getJSONContentType() and com.cloud.api.ApiServer.isSecureSessionCookieEnabled() had to be added in the interface (org.apache.cloudstack.api.ApiServerService, interface implemented by class ApiServer).

    Removed unused code from com.cloud.api.ApiServer
    
    Removed “_” from variables names, private variables with “_” at the
    beginning is common in C++ but not in Java.
     
    Removed unused methods from ApiServer:
    -  com.cloud.api.ApiServer.setPluggableServices(List<PluggableService>):
    This method can be removed and replaced by the annotation @Inject in the
    variable pluggableServices (before _pluggableServices.
     
    - com.cloud.api.ApiServer.getPluggableServices(): Unused method.
    - com.cloud.api.ApiServer.setApiAccessCheckers(List<APIChecker>): Can be
    replaced by the @Inject in the variable apiAccessCheckers (before
    _apiAccessCheckers).
    - com.cloud.api.ApiServer.getApiAccessCheckers(): Unused method.
     
    Methods and variables access level reviewed:
    - com.cloud.api.ApiServer.handleAsyncJobPublishEvent(String, String,
    Object): This method was private but the annotation @MessageHandler
    requests public methods, as can be seen in
    org.apache.cloudstack.framework.messagebus.MessageDispatcher.buildHandlerMethodCache(Class<?>),

    were changed to private.
     
    Changed variables and methods from static to non-static (if possible):
    As some variables/methods are used just by one object of this class,
    instantiated by Spring, they were changed to non-static.

    ApiServer.<staticMethodName> to _apiServer.<methodName> that refers to
