Pagination in various OpenStack_2_NodeDriver methods
The default max_limits for OpenStack is 1000. If you have more than 1000
resources (i.e. snapshots) then everything but the newest 1000 will not be
listed. If you set the max_limits lower even less will not be returned, etc.
This change implements pagination for ex_list_snapshots, ex_list_ports, and
list_volumes in the OpenStack_2_NodeDriver. This PR builds on top of (and
contains) https://github.com/apache/libcloud/pull/1242.
Inspired by `_paginated_request` in the [DigitalOcean
driver](https://github.com/apache/libcloud/blob/bc097ffe5b04990e0ca302231388ee7d5d6fe911/libcloud/common/digitalocean.py#L176)
before:
```
In [3]: out = conn.list_snapshots()
In [4]: len(out)
Out[4]: 1000
```
after:
```
In [3]: out = conn.list_snapshots()
In [4]: len(out)
Out[4]: 53098
```
before:
```
In [6]: out = conn.list_volumes()
In [7]: len(out)
Out[7]: 1000
```
after:
```
In [3]: out = conn.list_volumes()
In [4]: len(out)
Out[4]: 4876
```
before:
```
In [8]: out = conn.ex_list_ports()
In [9]: len(out)
Out[9]: 123
```
after:
```
In [5]: out = conn.ex_list_ports()
In [6]: len(out)
Out[6]: 123
```
Note that this does not affect the OpenStack_1_1_NodeDriver and those still
won't be paginated and will not return anything except for the 1000 most recent
resources.
