- If users specify a single timestamp (startTs==endTs) when performing
a sensor query through dcdbquery or libdcdb, a fuzzy sensor query is
performed, and the closest sensor reading to the target timestamp is
returned

- A regular expression (jobFilter) can be applied to the jobs' nodelists
to identify the jobs that need to be treated by each collectagent in a
cluster
- By default only the first node in the nodelist is considered, but this
behavior can be customized

- An operator naming conflict prevented the option from working correctly

- Integrated changes to the stop mechanism
- Also re-worked the interface to have the same execOn* methods as Sensor Groups

- 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

Only minor improvements today
It seems that dynamic symbol address are currently not computed correctly

-detect a subset of symbols in shared library even if stripped
-fix a critical bug which lead to skipping of function symbols
-both changes increase the memory overhead drastically...

-fixes on both sides
-finish first implementation of pusher plugin
-still requires quality of life improvements

- querySensor does not return NULL pointers anymore, but always
the "buffer" input argument
- the previous implementation was more descriptive of error statuses,
but much more prone to leaking memory in case of improper usage
- Also fixed a warning in the MSR plugin

-Fixes and improvements to Caliper service
-Start work on Pusher plugin

Local work will be merged to branch

- Fixed a bug in the collectagent that caused the QueryEngine to not
be treated correctly, due to a missing linking flag

- Fixed a bug associated to virtual sensor queries under the new schema
- Symbol for scaling in dcdbquery is now '@'

-service stores snapshot data now in shared memory
-Caliper service finished for the moment
-Pusher plugin adaption outstanding...

- Fixed a bug in the Filesink plugin that caused occasional crashes
- Fixed a bug in the Pusher REST API that prevented plugin reloads
for operators

- Make clean might be required

-fixed symbol address calculation
