This change introduces max_set_duration, the duration for the value
as max_set_size. max_set_size can keep the db size, however, sometime
max_set_size allows to contain old data. max_set_duration can keep
the latest data.

tail plugin: Allow to set "bucket" metrics type
When several distributions needs to be calculated in one 'tail' instance,
all their metrics will be reported as single 'bucket' type with the same plugin instance value.
That is confusing and this patch allows to split these metrics to their own types.

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.

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,
