dcmanager: Missing release version validation

[srana]

Brief Description
-----------------
dcmanager commands accept invalid release parameters

Severity
--------
<Minor: System/Feature is usable with minor issue>

Steps to Reproduce
------------------
create prestage orchestration strategy for subclouds

use a non valid release version

dcmanager prestage-strategy create --release xx --sysadmin-password ...
+---------------------------+----------------------------+
| Field | Value |
+---------------------------+----------------------------+
| strategy type | prestage |
| subcloud apply type | None |
| max parallel subclouds | None |
| stop on failure | False |
| prestage software version | xx |
| state | initial |
| created_at | 2023-08-29T15:53:20.000091 |
| updated_at | None |
+---------------------------+----------------------------+
[sysadmin@controller-0 ~(keystone_admin)]$
[sysadmin@controller-0 ~(keystone_admin)]$
[sysadmin@controller-0 ~(keystone_admin)]$ dcmanager prestage-strategy show
+---------------------------+----------------------------+
| Field | Value |
+---------------------------+----------------------------+
| strategy type | prestage |
| subcloud apply type | None |
| max parallel subclouds | None |
| stop on failure | False |
| prestage software version | xx |
| state | initial |
| created_at | 2023-08-29 15:53:20.000091 |
| updated_at | None |
+---------------------------+----------------------------+

Expected Behavior
------------------
The prestage strategy should be rejected

Actual Behavior
----------------
the prestaged stragegy is created

Reproducibility
---------------
100% reproducible

    Add sw version validation to all release param endpoints

    Incorporate the existing release version validation with
    all the dcmanager operations/commands endpoints that allow
    the user to specify a release version:
     - subcloud add
     - subcloud prestage
     - subcloud redeploy
     - subcloud deploy show
     - subcloud deploy resume
     - subcloud deploy create
     - subcloud deploy install
     - prestage-strategy create
     - subcloud-backup restore

    Please note that the "subcloud deploy upload" release
    validation was addressed in a previous change [1].

    These changes add the validate_release_version_supported check
    (previously introduced [1]) to all the endpoints that
    consume a release parameter. This is done to check
    whether a specified release version is supported by the
    current active version.

    [1] https://review.opendev.org/c/starlingx/distcloud/+/891911

    Test Plan:
    For each command listed above, test the
    release parameter (--release):
        1. PASS: Verify that the current active version is
           accepted as a valid parameter.
        2. PASS: Verify that all the supported upgrade versions
           in /usr/rootdirs/opt/upgrades/metadata.xml are accepted
           as a valid release parameter.
        3. PASS: Verify that any upgrade version that's not included
           in metadata.xml is rejected with an error
           "<release> is not a supported release version". The only
           exception to this is the current active version, it must
           always be valid.
        4. PASS: Delete all the "supported_upgrades" elements in
           metadata.xml and verify the error
           "Unable to validate the release version" is printed.
        5. PASS: Delete metadata.xml and verify that
           "Unable to validate the release version" error is printed.
        6. PASS: Verify that the current active version is valid
           regardless of metadata.xml file and its contents.
        7. PASS: Exclude the release parameter and verify that the
           command is successful (completed
           with the current active version).
