[DOC] wrong install command for auth_pam plugin

[Przemek]

Seems that the command to load PAM Authentication Plugin has changed in recent versions, and this documentation is no longer valid:
http://www.percona.com/doc/percona-pam-for-mysql/installation.html#installing-server-side-plugin

Server version: 5.5.33-31.1 Percona Server (GPL), Release rel31.1, Revision 566

mysql> INSTALL PLUGIN auth_pam_server SONAME 'auth_pam.so';
ERROR 1127 (HY000): Can't find symbol 'auth_pam_server' in library

but this works:

mysql> INSTALL PLUGIN auth_pam SONAME 'auth_pam.so';
Query OK, 0 rows affected (0.00 sec)

mysql> show plugins;
+--------------------------------+----------+--------------------+-------------+---------+
| Name | Status | Type | Library | License |

| auth_pam | ACTIVE | AUTHENTICATION | auth_pam.so | GPL |
+--------------------------------+----------+--------------------+-------------+---------+

Same is true for 5.6:

mysql> show variables like 'version%';
+-------------------------+------------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------------+
| version | 5.6.13-rc60.5 |
| version_comment | Percona Server (GPL), Release 60.5 |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+------------------------------------+
4 rows in set (0,00 sec)

This is the command that works:

 INSTALL PLUGIN auth_pam SONAME 'auth_pam.so';

Both 5.5 and 5.6 docs have the correct command:
http://www.percona.com/doc/percona-server/5.5/management/pam_plugin.html
http://www.percona.com/doc/percona-server/5.6/management/pam_plugin.html

So marking it as Invalid for those two
