[BUG] add ldap user button missing

[DaanHoogland]

Describe the bug
when a ldap server has been configured, in the old UI a button for adding an ldap user in the account overview is shown.

In primate this is not the case:

To Reproduce
Steps to reproduce the behavior:

1. configure an ldap server according to http://docs.cloudstack.apache.org/en/latest/adminguide/accounts.html#using-an-ldap-server-for-user-authentication
2. login
3. go to accounts overview
4. considder adding an ldap user according to the oldest method; manual import

Expected behavior
a button is expected.

Screenshots
see description.

Desktop (please complete the following information):

• OS: [e.g. Windows, Mac, iOS, Android with device/screen details if applicable]
• Browser [e.g. chrome, safari]
• Version [e.g. 22]

Additional context
Note that this is very minor as manual import is not the preferred way to maintain ldap users.

@DaanHoogland You can find the Add LDAP Account button at the next of the Add Account button (screenshot)

@utchoang @rhtyd Would it be better to make it explicit like the add account button ?

[utchoang]

@davidjumani @rhtyd Do you think it is good?

@utchoang LGTM! @DaanHoogland ^^

@utchoang @davidjumani , i am not partial on how it would be implemented as long as it is visible to an ignorant user looking for it. I remember some talk a while ago about making it an option after pressing the add account button. the above looks clear to the user at least.

@utchoang Please go ahead and raise a PR for the change. Thanks
