[PATCH lttng-tools] Tests: Added autoloading session test cases

[Anders Wallin]

lttng-sessiond can auto load sessions at startup;
- with "--load" option to lttng-sessiond, load one file
  or all sessions files in that directory
- from session files in $LTTNG_HOME/.lttng/sessions/auto/
- from session files in $sysconfdir/lttng/sessions/auto

This test case validate the two first scenarios.

Yes, lttng-tools 2.10.4 is broken when having auto-load sessions, see
https://lists.lttng.org/pipermail/lttng-dev/2018-May/028014.html

I will add a longer commit message

running when starting the tests.

Should reflect the overall test: "Auto load session(s)"

The stop_lttng_sessiond should be moved at the end of each sub test.

Put stop_lttng_sessiond here.

Use "mktemp -d" here.

Make sure to remove the complete LTTNG_HOME directory.
