Bug Description

Brief Description
-----------------
During subcloud upgrade, failure can occur during remote install or data migration step for reasons such as misconfigurations, temporary network glitch. If this occurs, the subcloud deploy_status is set to install-failed/data-migration-failed respectively. This status change results in subcloud audit being skipped and the subcloud can never be deleted.

Severity
--------
Major

Steps to Reproduce
------------------
With the system controller running N+1 load and at least one subcloud running N load
- Create a subcloud upgrade strategy using the command "dcmanager upgrade-strategy create <subcloud-name>"
- Apply the upgrade strategy using the command "dcmanager upgrade-strategy apply"
- Induce a failure during upgrade simplex step by temporarily removing route to the subcloud bootstrap IP
- View the subcloud detail using the command "dcmanager subcloud show <subcloud-name>"

Expected Behavior
------------------
The affected subcloud should be listed as "offline".

Actual Behavior
----------------
The affected subcloud would alaywas be listed as "online" as dcmanager subcloud audit skips auditing any subclouds with deploy_status not equal to 'deploy-failed', 'deploying' or 'complete' status.

Reproducibility
---------------
Reproducible

System Configuration
--------------------
Distributed Cloud

Branch/Pull Time/Commit
-----------------------
Jun 30th master build

Last Pass
---------
I don't think there an existing test case for this specific scenario.

Timestamp/Logs
--------------
N/A, there are no error logs. This is a design oversight.

Test Activity
-------------
Developer Testing

Workaround
----------
Change the deploy_status of the affected subcloud to 'complete' in the database, wait up to 20s for the subcloud audit to resume auditing the affected subcloud.

Bart, this is the block of code that causes it to skip the audit

 if (subcloud.deploy_status not in
                    [consts.DEPLOY_STATE_DONE,
                     consts.DEPLOY_STATE_DEPLOYING,
                     consts.DEPLOY_STATE_DEPLOY_FAILED]):
                LOG.debug("Skip subcloud %s audit, deploy_status: %s" %
                          (subcloud.name, subcloud.deploy_status))
                continue

Should failed be the only one removed from the list. I am assuming 'done' and 'deploying' will never get stuck.

    Allow audit for additional deploy status failed states

    Adding the deploy status failure states to the list of auditable
    criteria for subclouds. This allows subclouds to be set to
    offline by the audit rather than skipping the audit for them.

Marking as stx.5.0 as this deals with a specific failure scenario. There is no need to port to the stx.4.0 branch at this time.

    Format the IP addresses in payload before adding a subcloud

    The IPv6 addresses can be represented in multiple formats. As IP
    addresses are stored as text in database, ansible inventory and
    overrides, this commit converts the IP addresses in payload to
    standard text format of IPv6 address during adding a new subcloud.

    Tested with installing and bootstrapping a new subcloud(RVMC
    configured) with the correct IPv6 address values, but with
    unrecommended upper case letters and '0'. The addresses are
    converted to standard format in database, ansible inventory and
    overrides files.

    Delete existing vim strategy from subcloud during patch orch

    When dcmanager creates a patch strategy, if a subcloud has an
    existing vim patch strategy, it will attempt to re-use
    that strategy during its patching phase, which may result in an
    error.

    This commit deletes the existing vim patch strategy in
    a subcloud, if it exists, so it can be re-created.
    If the strategy cannot be deleted, orchestration fails.

    Adding activation retry to upgrade orchestration

    When performing an activation, the keystone endpoints may not
    be accessible in the subcloud due to the asyncronous way that
    cert-mon can trigger a restart of keystone.

    This would have occasionally resulted in the upgrade activation
    failing to be initiated, and orchestration needing to be invoked
    again to resume.

    This 'hack' adds retries and sleeps to the initial
    activation action.

    Fix subcloud show --detail command related issues

    If the subcloud is offline, the command stalls and eventually returns
    the "ERROR (app)" output. If the subcloud is online, the oam_floating_ip
    info is excluded from the output when the subcloud id instead of subcloud
    name is specified.

    This commit fixes both of the above issues.
