Bug Description

Brief Description
-----------------
After a single upload of ~900MB patch is complete, /scratch usage jumped from 3% to 26%. The temporary files that opened by the third-party libraries are not closed after upload is completed. As a result, a few of large patch uploads will exhaust /scratch space.

Here are the deleted files held by one of the patching-api-proxy workers
dcorch-ap 118991 root 4u REG 253,0 941866267 15 /scratch/patch-api-proxy-tmpdir/tmpO8BC0c (deleted)
dcorch-ap 118991 root 9u REG 253,0 941866434 14 /scratch/patch-api-proxy-tmpdir/tmpwAcd6Z (deleted)

A change is required in the patch-api-proxy process to close any temporary files that used to upload a large patch.

Severity
--------
Major

Steps to Reproduce
------------------
Install DC system with 1 or 2 subclouds, upload a large patch using SystemController region:

sw-patch --os-region-name SystemController upload LARGE_patch_name.patch

Expected Behavior
------------------
The system resources that used for upload free up after upload is completed.

Actual Behavior
----------------
Two temporary files are not released.

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

System Configuration
--------------------
Distributed Cloud with 2 subclouds

    Close any temp files after upload a patch

    Add a cleanup routine in the patch-api-proxy to close
    any temporary files that opened by third-party libraries,
    during a patch upload.

    Verified that the temp files are close and /scratch
    usage is not increased after a few of large patch
    upload.

    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.
