adds the bigip_ucs module (#26663)

This module allows you to load existing UCS files onto a BIG-IP
system

Unit tests are provided. Integration tests can be found here

+module: bigip_ucs
+short_description: Manage upload, installation and removal of UCS files.
+description:
+   - Manage upload, installation and removal of UCS files.
+version_added: "2.4"
+options:
+  include_chassis_level_config:
+    description:
+      - During restore of the UCS file, include chassis level configuration
+        that is shared among boot volume sets. For example, cluster default
+        configuration.
+    choices:
+      - yes
+      - no
+  ucs:
+    description:
+      - The path to the UCS file to install. The parameter must be
+        provided if the C(state) is either C(installed) or C(activated).
+        When C(state) is C(absent), the full path for this parameter will be
+        ignored and only the filename will be used to select a UCS for removal.
+        Therefore you could specify C(/mickey/mouse/test.ucs) and this module
+        would only look for C(test.ucs).
+  force:
+    description:
+      - If C(yes) will upload the file every time and replace the file on the
+        device. If C(no), the file will only be uploaded if it does not already
+        exist. Generally should be C(yes) only in cases where you have reason
+        to believe that the image was corrupted during upload.
+    choices:
+      - yes
+      - no
+  no_license:
+    description:
+      - Performs a full restore of the UCS file and all the files it contains,
+        with the exception of the license file. The option must be used to
+        restore a UCS on RMA devices (Returned Materials Authorization).
+    choices:
+      - yes
+      - no
+  no_platform_check:
+    description:
+      - Bypasses the platform check and allows a UCS that was created using a
+        different platform to be installed. By default (without this option),
+        a UCS created from a different platform is not allowed to be installed.
+    choices:
+      - yes
+      - no
+  passphrase:
+    description:
+      - Specifies the passphrase that is necessary to load the specified UCS file.
+    choices:
+      - yes
+      - no
+  reset_trust:
+    description:
+      - When specified, the device and trust domain certs and keys are not
+        loaded from the UCS. Instead, a new set is regenerated.
+    choices:
+      - yes
+      - no
+  state:
+    description:
+      - When C(installed), ensures that the UCS is uploaded and installed,
+        on the system. When C(present), ensures that the UCS is uploaded.
+        When C(absent), the UCS will be removed from the system. When
+        C(installed), the uploading of the UCS is idempotent, however the
+        installation of that configuration is not idempotent.
+    default: present
+    choices:
+      - absent
+      - installed
+      - present
+notes:
+   - Requires the f5-sdk Python package on the host. This is as easy as
+     pip install f5-sdk.
+   - Only the most basic checks are performed by this module. Other checks and
+     considerations need to be taken into account. See the following URL.
+     https://support.f5.com/kb/en-us/solutions/public/11000/300/sol11318.html
+   - This module does not handle devices with the FIPS 140 HSM
+   - This module does not handle BIG-IPs systems on the 6400, 6800, 8400, or
+     8800 hardware platform.
+   - This module does not verify that the new or replaced SSH keys from the
+     UCS file are synchronized between the BIG-IP system and the SCCP
+   - This module does not support the 'rma' option
+   - This module does not support restoring a UCS archive on a BIG-IP 1500,
+     3400, 4100, 6400, 6800, or 8400 hardware platform other than the system
+     from which the backup was created
+   - The UCS restore operation restores the full configuration only if the
+     hostname of the target system matches the hostname on which the UCS
+     archive was created. If the hostname does not match, only the shared
+     configuration is restored. You can ensure hostnames match by using
+     the C(bigip_hostname) Ansible module in a task before using this module.
+   - This module does not support re-licensing a BIG-IP restored from a UCS
+   - This module does not support restoring encrypted archives on replacement
+     RMA units.
