ci/lava: Use CI_JOB_TIMEOUT instead of separate variable
The CI_JOB_TIMEOUT
variable is the GitLab-defined job timeout in
seconds.
Use this variable in LAVA instead of the separate JOB_TIMEOUT
,
which was intended to represent the test phase timeout (job timeout
minus 5 minutes), but was often overlooked.
I've verified that the CI_JOB_TIMEOUT
is correctly parsed and that a longer job doesn't get cut short either.
I decided to competely delete JOB_TIMEOUT
, because it was both confusing and error-prone. There should be no reason to go with a value different than CI_JOB_TIMEOUT
- 5 minutes.
