[lttng-dev] [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.
