LDAP API lacks timeout options leading to bad login experiences

[TheWitness]

Describe the bug

The LDAP API in php provides two timeout options for both network (syn) and bind. The default is approximately two minutes. These defaults are too high and should be reduced or rather be configurable.

To Reproduce

Steps to reproduce the behavior:

1. Set your primary server to a host that is printable, but down

2. Logout of Cacti

3. Attempt to login

4. See error

Expected behavior

Cacti should fail over to the second server if the syn does not come back in two seconds. This should be approximately the same for the connect.

Just remember that timeouts for searching a directory may need to be longer since traversing can be slower. That happens at bind or search stages because of the user information. 120 seconds though is too longer a default. If someone needs that, it should be configurable I agree.

[TheWitness]

Hmm, the syn should be quick, the bind may take longer. Should we have two settings then?

[TheWitness]

Going to make these global settings. We can incorporate the domains plugin in 1.3.
