Fix issue #673: incorrect content length reporting (#674)
Without regexp validations, the current code reads the response from the
server in order to figure out the number of bytes we received. With
regular expression validations, it's necessary to read the whole
response in order verify it if matches or not. In this case, since the
response is completely consumed, the current code is reporting a length
of 0.
Modify the code so that we can keep track of the content length in
either case: wrap the io.ReadCloser that corresponds to the response
body with another io.ReadCloser that keeps track of the number of bytes
read. After completely consuming the reponse, the wrapper is able to
report the total number of bytes read.
Add TestContentLength that checks the content lenght is reported
correctly.
Rework existing TestFailIfBodyMatchesRegexp to reduce repetiiton; add
expectations to avoid regressing issue 673.

prober/tls: fix probe_ssl_last_chain_expiry_timestamp_seconds (#681)
* prober/tls: fix probe_ssl_last_chain_expiry_timestamp_seconds
This metric should report the earliest expiry of the chain that expires
the latest out of all the verified chains. Presently, it reports the
earliest expiry of the chain that expires first.
The current test for this metric was using an expired root certificate which
is omitted from the verified chain, so the test was passing despite this
bug. I've changed it to use a root that is still valid but expires before a
root held by the client.
* prober/tls: improve verified cert test
Include the older root certificate in the chain presented by the server
as well as in the client root CAs. This ensures that the peer
certificate metric identifies the older root CA as the earliest expiry
while it is ignored by the verified metric in favour of the longer-lived
chain.

Expose probe_dns_duration_seconds metric (#662)
* Expose probe_dns_duration_seconds metric
This follows the same pattern as probe_http_duration_seconds and
probe_icmp_duration_seconds: it captures the time it takes to perform
the actual request, excluding the time it takes to set up things.
probe_duration_seconds includes the time to perform the request as well
as all the time it takes to set it up. probe_dns_lookup_time_seconds
refers to the time it takes to resolve the target's address, so it
doesn't capture the time it takes to make one request for that target.
Follow probe_http_duration_seconds and add a "phase" label to
probe_dns_duration_seconds, which splits the time it takes to complete
the check into "resolve" (time to resolve the target name), "connect"
(time to connect to the DNS server) and "request" (time to send the
query and retrieve the response).

Empty in YAML means null. (#440)
The null then overrides the default config. Avoid this
in the example config file.

prober: icmp: Initialize ID and sequence to random values (#412)
This should help preventing issues with some network devices that have
trouble NATing ICMP packets with the same ID and sequence nubmer but a
different source IP address.
Currently, this can happen if the blackbox_exporter runs in a container
(the ID is set to the PID, which is typically 1 in a container), and
serveral blackbox_exporters are restarted at the same time (the sequence
numbers are reset to zero and stay in sync).
This commit sets the ICMP echo ID to a random value if the PID is 1, and
initializes the sequence number at a random offset.
See #411 for details.
