Description of problem:

Feel free to consider this an RFE or BUG as applicable but I am reporting this as a bug here.

We have two Export buttons available in 

Hosts --> Content Hosts page

    ( This works and exports the same data we can see in UI )

Hosts --> All Hosts page  

    ( This one does not exports the same set of data as visible in UI )




Version-Release number of selected component (if applicable):

Satellite 

  6.13 ( Snap 9 )
  6.12
  6.11
  6.10


How reproducible:

Easily 


Steps to Reproduce:

1. Install a Satellite 6.13 ( or any other versions mentioned )
2. Go to Hosts --> All Hosts page and note down the column names. 
3. Click on Export and Check the columns downloaded CSV file
4. Click on "Manage Columns" and make the following modifications before saving it.

    ** Unselect the Comment, Owner and RH Cloud options.
    ** Select the IPv4 Address inside Network category 

5. Note the change in columns in the All Hosts page now. 

6. Repeat Step 3



Actual results:

On Step 2:

Power	Recommendations	Name	Operating system	Model	Owner	Host group	Last report	Comment

On Step 3:

Name	Operatingsystem	Compute Resource Or Model	Hostgroup	Last Report

On Step 5:

Power	Name	IPv4 address	Operating system	Model	Host group	Last report

On Step 6:

Name	Operatingsystem	Compute Resource Or Model	Hostgroup	Last Report



Expected results:

Whatever Columns we can see for Hosts in "All Hosts" page, Those SHOULD BE exported in the CSV instead of only exporting a fixed set of data i.e.

Name	Operatingsystem	Compute Resource Or Model	Hostgroup	Last Report

Specifically when we give users the choice to customize what they want to see on that page via "Manage Columns", I am positive that users will try to export that data as well, and for that "Export" button needs to be able to fetch the expected data properly.
