Revisit logging decisions

• Log folder now under release so along the microacrh folders
• log files are of two kinds, tee output from spack_setup.sh for each toolchain and output from the installer script
• outputs from the installer script have the name structure {dev-23a}_{microarch}_{date}.log
• teed log files follow the name {dev-23a}_{microarch}_{date}_{specific_toolchain}.log
• The names are so chosen in order to have neat output on an ls and easier to tab complete
• the installer script log logs:
  • metadata like mpsd_os mpsd_microarch toolchains requested buildtime etc enclosed with metadata tags (see #6 (closed))
  • output from the logging module
  • file names of the teed log files to refer to at each stage and
  • at the end status installation of each requested toolchain

Changes from discussions from 06/06/23:

• installer_log_file structure: {dev-23a}_{microarch}_{date}_{cmd}.log
• build_log_file structure: {dev-23a}_{microarch}_{date}_{specific_toolchain}_{install|remove}.log

A reinstall creates both the logs for remove and install
