swap plugin: Added `ReportIO` option
lxc/lxd containers at the moment cannot properly report the swap io (the corresponding /proc/vmstat are not virtualized), so added an option to disable that reporting.
Enabled by default.

openvpn: reworked status file parser
* Added detection of status fields index by parsing 'HEADER' lines.
This allows to support status files from latest OpenVPN-2.4 and possible from future versions;
* Fixed a bug with OpenVPN status file version 3 where delimiter is 'tab' (not space or comma);
* Status file version detection was moved from configuration callback to read callback;
* Now 'plugin_register_complex_read()' is used for registering read callback.
To detect cflags and libs use the sometimes provided pkg-config for
libdpdk. That avoids build errors on systems where special flags are
needed and provided by dpdk via pkg-config, but not yet considered by
the collectd build system.

configure.ac: dpdk: tolerate no pkg-config
Since pull request #2400 pkg-config works great for dpdk, but not if
there is no pkg-config around at all.
To fix that the PKG_CHECK_MODULES macro needs to define a valid fourth
argument, otherwise it will error out.
This closes 2404

configure.ac: dpdk: append DPDK_CFLAGS to LIBDPDK_CPPFLAGS
In some way it is bad naming in pkg-config - it is always some sort of
conflated ldflags + libs and cppflags + cxxflags + cflags.
Due to that to work correctly we append DPDK_CFLAGS (if defined by
pkg-config) to LIBDPDK_CPPFLAGS as well.
This intentionally does not add those CFLAGS specified by a user to
allow full override and fully separated CLFAGS/CPPFLAGS if needed.

openldap: Fix plugin shutdown with connection failed
When plugin failes to connect to LDAP server, the `ldap_unbind_ext_s(st->ld)` is called.
According to `man 3 ldap_unbind_ext_s`, that call is used to free the resources contained in the ld structure.
When plugin shutdown, the `ldap_unbind_ext_s` called again, which causes coredump.
The plugin code was changed to set st->ld to NULL after `ldap_unbind_ext_s()` call.

openldap: Fixed possible dereference of NULL pointer
If `plugin_register_complex_read()` has failed, then `cldap_free` is called which set pointer to NULL.
That pointer is accessed by `cldap_shutdown()` callback later.

rrdtool plugin: Respect RandomTimeout while calling CacheFlush handler
The CacheFlush implementation does not respect RandomTimeout value.
All cache values, whose flush is deferred by RandomTimeout variance,
will be flushed. That can cause a partial or full cache flush,
depending on the value of RandomTimeout.

* The `upscli_cleanup()` should be called only at Collectd shutdown, excessive calls was removed;
* Added `upscli_init()` call if `ForceSSL` enabled.
* Added a check for duplicated values in `UPS` option.
