Stop using deprecated ssl.wrap_socket, and let unset key-file mean
the key is included in cert-file, as is done in python ssl module.
Also let the server crash if specified cert-file or key-file does
not exist, instead of silently falling back to non-TLS http.

Add 'socketpath' and 'abstract' options for path based unix sockets
and abstract unix sockets respectively.

This was sometimes causing false positives, for example if site have
only one hit and this hit takes more than one second, apdex is 0% and
promise failed, it seems useful to at least have a way to disable.

We are discussed on !1716 (comment 225941)
an idea of introducing a "minimal number of hits" parameter to not
detect this false positive on sites that are not accessed enough to
calculate a meaningful apdex.

Add `validate-parameters` options to slapconfiguration:jsonschema.
Accepted values are `all|main|shared|none`.
Default value is `all`.

When shared parameters validation is skipped, shared parameters are
left in `slave-instance-list`.

Add `set-default` options to slapconfiguration:jsonschema.
Accepted values are `all|main|shared|none`.
Default value is `none`.

These allow controlling whether default values of parameters that
where not provided by the user are set from the defaults given in
the JSON schema. The default behavior of the recipe is now not to
add any defaults. The new option allows adding all defaults, only
the defaults of the main instance, or only the defaults of shared
instances.
