Buildfix

[fengggli]

Major changes

1. now force out-of-tree build, see the updated README.md
2. add 'make install' support, after make install, all the .so will be in /build/install/lib. the common/component.cc will also load from that directory.

Minor changes

1. removed all the env(COMANCHE_HOME) in c/c++ source code, the COMANCHE_HOME is now set in the root CMakeLists.txt, and then auto-populated to the config_comanche.h during cmake (see config_comanche.h.in)
2. autogen.py and cmakeinclude are removed, they were intrusive to the source tree.. If we need slightly modify the source code, it's better done by config_comanche.h
3. fix: nvme_set reset support
4. add required entries for install-apts.sh

Note

• I temporarily disabled the build for "cluster"
• you need to rerun the install-apts.sh to add required packages
