Change installation disk space limit to 180Gi when using different disk for data.

[masteryyh]

Problem:

When selecting different disk for data, 250Gi limit for installation disk is too large.

Solution:

Change the limit to 180Gi when using different disk for data.

Related Issue:
harvester/harvester#4133

Test plan:

ISO Installation

Single Disk

1. Build an ISO from this branch;
2. Boot into the installer, the installer should limit the installation disk at 250Gi minimum.

Multiple Disk

1. Build an ISO from this branch;
2. Boot into the installer, and use the same disk for installation disk and data disk;
3. The installer should limit the installation disk at 250Gi minimum;
4. When choosing different disk for installation and data, the installer should limit the installation disk at 180Gi minimum.

PXE Installation

Single disk

1. Build artifacts from this branch;
2. Use PXE to install Harvester artifacts you just built, when disk is smaller than 250Gi it should not continue.

Multiple disk

1. Build artifacts from this branch;
2. Prepare a Harvester config yaml, use another disk for data;
3. Use PXE to install Harvester artifacts you just built, when installation disk is smaller than 180Gi or data disk is smaller than 50Gi the installer should not continue.

FYI: It's ready for review.

LGTM, thanks. Test Plan Passed. Just a small suggestion

LGTM, validated that both multi-disk and single-disk installation contains the correct partition.

LGTM, thanks. need squash commits

[bk201]

Excellent job; the merge makes the UX better. Can we wait for one more enter before proceeding to the next page when using a data disk? It's too rushed to jump to the next page immediately:

LGTM, thanks!

Just some nits, others LGTM.
Tested with two disks (200G, 512G), the result as below

LGTM, thanks for it! Let's wait for the CI.
