Support locking user with usermod if passwd is not available.
In some cases, the 'passwd' command might not be available, but
'usermod' might be. In debian systems both are provided by the
'passwd' package. In Redhat/Centos passwd comes from 'passwd' package
while 'usermod' comes from `shadow-utils`
This should just support either one with no real cost other than
the check.
cc_apt_pipelining: stop disabling pipelining by default
This was introduced due to Ubuntu using S3 mirrors, and S3 having a
buggy pipelining implementation. Those Ubuntu mirrors are no longer in
production and, furthremore, apt has also grown the ability to handle
servers with broken pipelining.
As such, we can stop disabling pipelining, which should result in
improved apt download speeds.
In test_ds_identify, don't mutate otherwise-static test data. When
running tests in a random order, this was causing failures due to
breaking preconditions for other tests.
In tests/helpers, reset logging level in tearDown. Some of the CLI
tests set the level of the root logger in a way that isn't correctly
reset.
For test_poll_imds_re_dhcp_on_timeout and
test_dhcp_discovery_run_in_sandbox_warns_invalid_pid, mock out
time.sleep; this saves ~11 seconds (or ~40% of previous test time!).
Encrypted data bags require a secrets file to be present to
decrypt, and the location of the file must be configured the
Chef client configuration file, client.rb.
This update enables cloud-init's chef module to update that
setting in client.rb.
