Use the "base" and "basic" CI test references.

This should be the last CI-reference-switching-related commit in the
history of this repository, as in the future the pointed test should be
the one to move.

[fix] Added execute file permissions to autogen.sh

See merge request !9

[feature] adding application uuid to progress messages.

See merge request !8

[fix] fixing extra quotes in the message format.

See merge request !7

removing extra quotes, adding 'api' field, 'event' -> 'type'

[ci] Offloading CI versioning to argotest.

See merge request !6

This commits simplifies the CI setup for this repository, offloading all
complexity to the "argotest" repository.

The ci setup was also changed to better isolate library building
from integration tests.

Match the changes made to the downstream API on the NRM side.

This source branch should not deleted until nrm/master:.integration.nix
does not point to it anymore.

Added integration testing to the CI pipeline.

See merge request !4

This commits adds a gitlab-ci integration test target, and the
.integration.nix file, which specifies the exact test version pinning to
use. The gitlab-ci file is also renamed to its proper name, and the
non-passing, previously disabled "make:generic" test is commented out.
For the record, this 'build' test is strictly contained in the integration
tests.

Match the changes made to the downstream API on the NRM side.

[refactor] remove C++, add autotools, pkg-config

See merge request !1

This patch cleans up the code, use better names for the headers, remove
the last bits of C++ and add autotools to compile the library.

This patch also splits the PMPI library into a separate .so, to make it
easier to only deal with the core downstream API.

Phase context aggregation was failing as the damper unit was in seconds
insted of nano seconds. This has been fixed now

See Issue #2

Allow users to annotate phases to control transmission of application
context information.

A phase can be skipped now by setting NRM_SKIP to non-zero value.

See Issue #3

Added aggregation support to MPI_NRM library. It uses the modified
downstream API to transmit compute and total time of a phase.

The NRM damper value is used for aggregation, and phases smaller than
this value are aggregated. The _aggregation parameter keeps track of
the number of phases that are aggregated for the total time to be
greater than the damper value.

See Issue #2

Instead of transmitting clock times, the downstream API is changed to
allow application side aggregation of phases below a damper value. This
is to decrease the frequency of messages sent.

The downstream API will now transmit the actual time a CPU spent in
computation and the total phase time.

See Issue #2

Removed all the measurement capability as it will be handled by the NRM.
Also, update Makefile and README to reflect this change

See Issue #1
