Refactoring methods in LdapClient and Authorizer

[longshuicy]

Backwards tracing:

1. No need for this LdapClient to exist anymore

In this file:

incore-services/server/incore-common/src/main/java/edu/illinois/ncsa/incore/common/auth/LdapClient.java

Line 12 in 04c33a1

import edu.illinois.ncsa.incore.common.users.LdapUserInfo;

2. add additional userGroups parameter to private List<Space> getSpacesUserCanRead(List<Space> spaces, String username) {

add additional parameter List<String> userGroups

3.add additional userGroups parameter to private boolean canUserAccessSpace(Space space, String username, PrivilegeLevel privilegeLevel) {

add additional parameter List<String> userGroups

Further pass in that userGroups to getGroupSpecificPrivileges(username, space.getPrivileges())
e.g.
https://github.com/IN-CORE/incore-services/blob/04c33a1ce6ca6e99b2cb88de61e5b8883a3b6c12/server/incore-common/src/main/java/edu/illinois/ncsa/incore/common/auth/Authorizer.java#LL303C19-L303C19

4. modify getGroupSpecificPrivileges(username, space.getPrivileges())

private Set<PrivilegeLevel> getGroupSpecificPrivileges(String user, Privileges spec, List<String> userGroups) {
...
//            Set<String> userGroups = ldapClient.getUserGroups(user);

Commented out the part that fetch userGroups from ldap

5. modify getGroupSpecificPrivileges(username, space.getPrivileges()) continue

incore-services/server/incore-common/src/main/java/edu/illinois/ncsa/incore/common/auth/Authorizer.java

Line 235 in 04c33a1

if (userGroups.contains(System.getenv("AUTH_LDAP_VIEW_ALL"))) {

This should change to check if incore_admin or incore_ncsa exist in the group or not; if exist, consider to grant them the same view all privileges

6. modify public boolean isUserAdmin(String username) {

pass List<String> userGroups to that function
No need to check LDAP but instead check for the same incore_admin and/or incore_ncsa

incore-services/server/incore-common/src/main/java/edu/illinois/ncsa/incore/common/auth/Authorizer.java

Line 204 in 04c33a1

return userGroups.contains(System.getenv("AUTH_LDAP_ADMINS"));

7. pass List<String> userGroups to public Set<PrivilegeLevel> getPrivilegesFor(String user, Privileges spec) {

8. pass List<String> userGroups to canRead, canWrite, canDelete etc

9. wire in the groups info from every single controller. Documented in another task
