Update crashDumpMgr to source config from envfile

This commit updates the crashDumpMgr service in order to:
- Cleanup of current service naming and packaging to follow the
  standard Linux naming convention:
    - Repackage /etc/init.d/crashDumpMgr to
      /usr/sbin/crash-dump-manager
    - Rename crashDumpMgr.service to crash-dump-manager.service
- Add EnvironmentFile to crash-dump-manager service file to source
  configuration from /etc/default/crash-dump-manager.
- Update ExecStart of crash-dump-manager service to use parameters
  from EnvironmentFile
- Update crash-dump-manager service dependencies to run after
  config.service.
- Update logrotate configuration to support the retention polices of
  the maximum files. The “rotate 1” option was removed to permit
  crash-dump-manager to manage pruning old files.
- Modify the crash-dump-manager script to enable updates to the
  max_files parameter to a lower value. If there are currently more
  files than the new max_files value, the oldest files will be
  deleted the next time a crash dump file needs to be stored, thus
  adhering to the new max_files values.

Test Plan:

PASS: Build ISO and perform a fresh install. Verify the new
crash-dump-manager service is enabled and working as expected.
PASS: 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.
PASS: Verify that the crashdump files are rotated as expected.
