Context:
In the CamBPM Jenkins shared library, the cambpmGetMatrixStages method dynamically generates a set of Stages. For this purpose, it utilizes the .ci/config/stage-types.yaml file (through the cambpmGetMavenInfo method).

Problem:
The .ci/config/stage-types.yaml file is read every time some Stage information is needed. Since there may be a large number of Stages, the number of reads becomes even larger.

AC:
Reduce the number of reads of this file (and possibly the CamBPM shared lib resources/cambpm/config/databases.yaml file).
