The test doesn't care about the instance state, just wants an
 arbitrary instance title.

This promise relates to resources local on the partition, which are files, and
they shall be available fast, thus make it failing immediately in case of
failure.

See merge request nexedi/slapos.toolbox!100

If there is no url parameter the promise fails, so simply switch to empty.

The check_url_available promise has been improved with the following
changes:

- The `http_code` parameter has been renamed `http-code` for consistency.
- The `check-secure` parameter has been removed. Users should specify
  `http-code = 401` instead.
- The `username` and `password` parameters have been added to optionally
  enable HTTP basic authentication.
- The logging output has been changed slightly.

Accept unicode value for `port` parameter

pc.ram key is used for the initial memory, and it can't be removed.

This promise generalizes the check_port_listening promise to include
AF_UNIX sockets in addition to AF_INET and AF_INET6 host/port sockets.

The socket family and address is deduced from the set of arguments:
- `host` & `port`: AF_INET or AF_INET6
- `pathname`: filesystem pathname address for AF_UNIX
- `abstract`: '\0' is prefixed to build an abstract AF_UNIX address

All other combinations of arguments are forbidden.

The promise creates a socket accordingly and attempts to connect to the
provided address. The promise fails if the connection fails.

The check_port_listening promise has been removed.

This reverts commit 4a992aaa.

runpromise takes arguments from command line, but also read some from
a config file, so indeed it is mandatory to know partition_folder's
value, but it is not mandatory to pass it as an argument from the
command line

So instead of a traceback we get a better error message
written by argparse. Also , it will print a better help
message

On python3 several views were not functional, because subprocess output was
retrieved as bytes, but manipulated as a string.

This adds a few tests for views, not complete because it would be too much time
consuming for now.

the behavior seems the same, default config in both cases is to trust one
level of proxy.

Monitoring is about states, not exact values, so report the states, as
otherwise it results with bloating databases, very long accesses to results
and long synchronisations.

Instead of many entries like:

http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: ERROR IP IP replied in 5.02s which is longer than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: ERROR IP IP replied in 5.03s which is longer than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: ERROR IP IP replied in 5.04s which is longer than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: ERROR IP IP replied in 5.01s which is longer than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in 0.08s which is shorter than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in 1.37s which is shorter than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in 0.09s which is shorter than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in 1.37s which is shorter than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in 0.09s which is shorter than maximum 5.00s

It's minimised to:

http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: ERROR IP IP replied in more time than maximum 5.00s
http://url/ : http_query: OK status code 302 on IPs IP elapsed_time: OK IP IP replied in less time than maximum 5.00s

This affects:

 * bot_status
 * http_query

Obviously some information are removed from the monitor, but anyway they are
just text entries and not parsable. So other approaches shall be used to make
graphs from those values, which is not covered by pure promise status.

Arguments passed to apachedex are complex, they contain quotes, backslashes,
spaces and they are propagated through several levels of buildout profiles
and scripts.
Simplify all this by relying on argparse ability of passing arguments from
a file. Users of this tool are now expected to generate a config file and
specify the path of this config file as an arguments.

This fixes division by 0.
