sru curtin 2021-02-18 - 21.2-0ubuntu1

[ <dannf> Should we request that the MAAS testing portion of curtin's
          SRU Special Case Exception be omitted for >= focal, since
          MAAS has migrated to a snap there, and MAAS PPAs provide
          their own curtin builds? ]

[ <dannf> This template is seeded by a cut & paste of the last SRU bug
          I found, bug 1881003. ]

== Begin SRU Template ==
[Impact]
This release sports both bug-fixes and new features and we would like to
make sure all of our supported customers have access to these improvements.

See the changelog entry below for a full list of changes and bugs.

[Test Case]
The following development and SRU process was followed:
https://wiki.ubuntu.com/CurtinUpdates

Curtin now contains an extensive integration test suite that is ran using
the SRU package for each releases. These suite has documentation here:
https://curtin.readthedocs.io/en/latest/topics/integration-testing.html

In order to avoid regression to existing MAAS product, the MAAS team will
run their continuous integration test against the curtin that is in
-proposed. A successful run will be required before the proposed curtin
can be let into -updates.

The curtin team will be in charge of attaching the artifacts and console
output of the appropriate run to the bug. Curtin team members will not
mark ‘verification-done’ until this has happened.

[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned integration tests are attached to this bug.
