Call odrefresh in VM from composd

composd needs to prepare the directory, run a fd_server, etc. then
request to run odrefresh in the VM.

`FdServerConfig` and `FdServer` are introduced to make starting a
fd_server from composd easier.

Also, add a testing command in composd_cmd.

Bug: 205750213
Test: atest ComposHostTestCases
Test: With some local hacks in ART, with SELinux disabled in the VM,
      odrefresh completed with exit code 80 and output files that
      look normal (at least sizes are).
