The remove_config() function only removes an exact match for
the configured instance.
This will allow removing plugin configuration when all config is
not known.
Use case: A compute node has been removed, so any host_alive
ping checks that are configured for it should be removed. But at
the time of removal the list of target_hostnames to match are
not known.

This patch removes the code that does the copy of /sbin/ip to
/usr/bin/monasca-agent-ip. There is a limitation with /sbin/ip
that limits copying it to a new name that is longer than
2 characters. The error is:
./monasca-agent-ip a
Object "nasca-agent-ip" is unknown, try "ip help".
As this is not working on RHEL,SLES, or Ubuntu this code
should be removed.

Currently we don't have any capability to monitor the internal TLS/SSL
certificates. i.e. SSL certificates used by MySQL for replication, RabbitMQ for
distribution, etc. The cert_check plugin is not adequate for this purpose
becaue it can only check on certficates over HTTPS endpoints. Furthermore,
checking on these internal certificates over the network is cumbersome
because the agent plugin would have to speak specific protocols.
This patch adds a cert_file_check plugin to detect the certificate expiry
(in days from now) for the given X.509 certificate file in PEM format.
Similar to cert_check plugin, this plugin will a metric
'cert_file.cert_expire_days' which contains the number of days from now the
given certificate will be expired. If the certificate has already expired,
this will be a negative number.

A powerful metric to watch for a swift cluster is the
number of handoff partitions on a drive on a storage node.
A build up of handoff nodes on a particular server could
indicate a disk problem somewhere in the cluster. A bottleneck
somewhere. Or better, when would be a good time to rebalance
the ring (as you'd want to do it when existing backend data
movement is at a minimum.
So it turns out to be a great visualisation of the health of
a cluster.
That's what this check plugin does. Each instance check takes
the following values:
ring: <path to a Swift ring file>
devices: <path to the directory of mountpoints>
granularity: <either server or device>
To be able to determine primary vs handoff partitions on a drive
the swift ring needs to be consulted. If a storage node stores
more then 1 ring, and an instance would be defined for each.
You give swift a bunch of disks. These disks are placed in what
swift calls the 'devices' location. That is a directory where a
mount point for each mounted swift drive is located.
Finally, you can decide on the granularity, which defaults to
`server` if not defined. Only 2 metrics are created from this
check:
swift.partitions.primary_count
swift.partitions.handoff_count
But with the hostname dimension a ring dimension will also be set.
Allowing the graphing of the handoff vs partitions of each ring.
When the granularity is set to device, then an additional
dimension to the metric is added, the device name (the name of
the devices mount point). This allows the graphing and monitoring
of each device in a server if a finer granularity is required.
Because we need to consult the Swift ring there is a runtime
requirement on the Python Swift module being installed. But
this isn't required for the unit tests. Making it a runtime
dependency means when the check is loaded it'll log an error
and then exit if it can't import the swift module.
This is the second of two Swift check plugins I've been working on.

Swift outputs alot of statsd metrics that you can point directly
at monasca-agents. However there is another swift endpoint,
recon, that is used to gather more metrics.
The Swift recon (or reconnaissance) API is an endpoint each of the
storage node servers make available via a REST API. This API can
either be hit manually or via the swift-recon tool.
This patch adds a check plugin that hits the recon REST API and
and send metrics to monasca.
This is the first of two Swift check plugins I'm working on.

To support python3 in the near future this was done:
* Removed dependency on supervisor.
* Added template configuration for systemd target that includes all
services.
* Added templates configuration for systemd service for every single
service.
* Changed monasca_setup to use the new templates.
In the meanwhile code was formated to cope with pep8 settings and some
other small changes were done to comply with pycodestyle and
pydocstring.
