Bug Description

[Impact]
The last netplan SRU (0.103-0ubuntu5~20.04.2) introduced a state tracking
feature, that regressed the 'netplan try' CLI command, if no such --state
argument is passed, making it fail with a error message like this:

An error occurred: 'NetplanApply' object has no attribute 'state'

This upload contains a fix to properly initialize the 'self.state' attribute in
all cases to avoid this problem.

[Test Plan]
In addition to runing & passing the full set of unit- and integration-tests
(that contains new tests to check for this regression), as described in
https://wiki.ubuntu.com/NetplanUpdates we want to run the following commands
to make sure the 'netplan try' command is working properly:

$ netplan try
$ [Ctrl+C] # to abort the waiting
=> Make sure it does not print a "An error occurred" message

$ netplan try
$ [Enter]
=> Make sure it does not print a "An error occurred" message

[Where problems could occur]
This upload contains changes to the CLI of netplan, if anything goes wrong it
could impact the interactive usage of 'netplan try'/'netplan apply' by the user.

[Other Info]
The full set of autopkgtest logs will be attached after the upload is accepted
into -proposed and the tests have been run on the official autopkgtest.u.c
infrastructure.

=== Original Description ===

I hava a freshly installed Ubuntu Server 20.04 LTS.
I am using a static IP config (100% sure it is correct, also the YAML is correct)

If you then enter "netplan try" I get this:
--------------------------------------------------------------------------------
Warning: Stopping systemd-networkd.service, but it can still be activated by:
systemd-networkd.socket

An error occurred: 'NetplanApply' object has no attribute 'state'

Reverting.
Warning: Stopping systemd-networkd.service, but it can still be activated by:
systemd-networkd.socket
--------------------------------------------------------------------------------

"netplan generate && netplan apply" does work.
I found some other people having these issues too on freshly installed 20.04 and 21.10 and online forums.

As a workaround you can execute the "netplan try" command as:
netplan try --state /etc/netplan

This will mitigate the problem for the time being.

Thank you @wdoekes for confirming it works on Focal!
