Regression in "lxd init" behavior in 2.0.11

[Stéphane Graber]

This is an SRU tracking bug for the fixes to two "lxd init" regressions in LXD 2.0.11.

1) Missing question about the ZFS pool name when creating a new pool.
2) Missing question about the LXD bridge configuration.

Both of those are part of our interactive workflow so didn't trip our automated testing and unfortunately didn't trip our manual testing either as were mostly focused on upgrades rather than validating that the initial configuration tool was asking all the expected questions.

This SRU should be rushed as those two issues make the initial configuration of LXD inconsistent with documentation and quite a bit harder for users to do.

# Testcase
Install LXD 2.0.11 on a clean system, run "lxd init", select "zfs" as the storage backend and accept to create a new pool. Confirm that you get asked for the pool name. Then later, check that you're asked to configure the LXD bridge and that answering yes causes a set of debconf prompts to show up.

# Regression potential
This only applies to new installations and has been manually tested already alongside the old LXD 2.0.10 to confirm that the behavior is now identical.

There is the possibility that we missed another regression in that code, but this fix would still be a good improvement.

Oh and it goes without saying that our manual testing plan got updated to better cover lxd init moving forward.

Noticed another issue when using the "dir" backend, an unrelated warning about missing profile is shown. I uploaded a follow-up upload to fix that too (fix is upstream and jenkins is happy).

Using this same bug to track this.

Confirmed all 3 fixes:
 - Running with dir backend doesn't show a warning anymore
 - Running with zfs backend asks for the pool name, uses the right default value and leads to a working pool
 - All runs now ask about network configuration

The verification of the Stable Release Update for lxd has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
