ldap3.ServerPool usage appears to be hardcoded

[drakej]

It's impossible to use this library without the ldap3.ServerPool functionality because it appears to be hardcoded into here.

I get raise LDAPServerPoolError('pools can be exhausted only when checking for active servers') but that's after I set LDAP_AUTH_POOL_ACTIVE = False.

I was definitely not expecting it to completely crash when changing a boolean default value like this. Is this an oversight or am I missing something obvious?

I'm using version 0.15.8
