Rename crashDumpMgr to crash-dump-manager

This review https://review.opendev.org/c/starlingx/metal/+/897593
updates the crashDumpMgr name to crash-dump-manager.

This commit updates the crashDumpMgr name accordingly.

Test Plan:
PASS: Build ISO and perform a fresh install. Add and apply new
crashdump service parameters and force a kernel
panic. Verify that after the reboot, the max_files, max_used,
min_available and max_size values are updated accordingly to the service
parameters values.
