Pusher: Refactor ConfiguratorTemplate once again. Replace partial template specialization with derived ConfiguratorTemplate for entities

- The interval field now defaults to the value inherited from the
sensor groups that the sensor belongs to
- Metadata blocks in templates can now be overwritten completely or
only in part

- Also added a "pattern" field to SensorMetadata class for consistency
with the DCDB::PublicSensor class

- Data is correctly parsed from DCDBPusher, sent as JSON, and received
by collectagents
- Integration in libdcdb is still pending

- Removed automatic assignment of sensor names to MQTT topics and vice
versa if either is empty
- All boolean checks now use the to_bool function

Create sensor names from mqttsuffix if not configured otherwise and vice versa. For sensor groups that use entities, create group name from entity name if not configured otherwise.

- If a subSampling value of 0 or lower is chosen for a sensor, it will
never be pushed out over MQTT/Cassandra and only kept in memory

- Decoupled the stop() and wait() methods
- A stop command is issued to all sensor groups, then a wait is performed
- Wait() now does busy waiting at a 10ms frequency and times out based
on the interval of the sensor group

- This plugin allows to write arbitrary sensor data to the local file system
- Removed the obsolete sink functionality in SensorBase
- Also fixed a minor bug concerning MQTT topic assignment in template analyzers

- use std::atomic_flag based spin lock for thread safety
- minor fixes and improvements

- Update/improve doxygen documentation
- Unify function name scheme of entity with SensorGroups
- Squash some TODOs

- Adapt Configurators:
  *Introduce partial template specialization in ConfiguratorTemplate
  *Move common logic to ConfiguratorInterface
  *Update and improve doxygen documentation
  *Adapt all plugin configurators
- Refactor printConfig of SensorGroups
- Minor improvements overall

- The MQTT topic of a sensor is now used to identify the file name of the
sink and is appended to the path given as input

Change perf-plugin implementation: Instead of duplicating sensorGroups per CPU only one group is used with duplicated sensors

- Auto-publish is now case insensitive with respect to the <sensor> and
<group> patterns
- If an invalid pattern was specified (missing <sensor> clause) the
configuration is aborted
- Checks for the uniqueness of sensor and group names have been
temporarily dropped as they interfere with templates and entities
(until we find a good solution for MQTT topics)

- Added some more indentation to make the configurations more readable
- Fixed one more warning in dcdbquery

- Boolean configuration options now all accept "true" and "on" keywords
- Cache interval and thread count parameters removed from the command-line
interface for consistency; these can still be set in the config files
like all other parameters
- global.conf file renamed to dcdbpusher.conf for consistency

- Checks on MQTT topics have been made generic in the MQTTChecker singleton
class under "common"
- MQTT topic checks are now performed also when plugins are reloaded; if
the checks fail, the plugin is cleared and left uninitialized
- All sensors in a plugin not satisfying the checks are logged now, not
only the first one
- Fixed a minor bug that resulted in msgrates of 0 under certain
compilers, due to type promotion in C++

- Added a 'common' directory where all shared code has been placed
- Analytics package has been moved out of dcdbpusher, now has its own makefile
- Some renaming here and there for uniformity
