Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1720643

Description of problem:
Default memory size for virtual machine is in Bytes (2147483648) while creating host
Also, the information icon for memory is unresponsive.

Version-Release number of selected component (if applicable):
Satellite version: 6.6.0 snap 6

How reproducible:
Always

Steps to Reproduce:
1. Navigate to Hosts and click on create hosts link.
2. Configure host parameters in host tab.
3. Switch to virtual machine tab.
4. Check the default memory size.
5. Click on the information icon for Memory.
6. Provide value in single digit eg. 2 or 4 and create host.

Actual results:
- Host parameters are configured properly. No issues seen.
- Virtual machine tab shows very high value for Memory - 2147483648 (which converts to 2 GB). This value is supposedly in Bytes considering 2GB to be the default value.
- Clicking on information icon is unresponsive. No information is shown to user about the unit of value.
- Single digit value is correctly applied - eg. if 2 is provided then host is provisioned with 2 GB memory.

Expected results:
- Memory size value should be in GB by default.
- Information icon should provide the unit info for memory size.
