User should not be allowed to add template settings if the template has "Read Instance settings from OVA" enabled

### problem

User should not be allowed to add template setting if the template has "Read Instance settings from OVA" enabled

### versions

ACS 4.22

### The steps to reproduce the bug

1. Register a template in Cloudstack with "Read Instance settings from OVA"

2 Currently, the exception is only thrown, if the user tires to add a uefi setting

3. A similar exception message should be shown if the user tries to add the following settings

### What to do about it?

Do not allow the addition of template settings if the template has "Read Instance settings from OVA" enabled

首先跟踪现有的验证逻辑：当启用 "Read Instance settings from OVA" 时，该逻辑会拒绝添加 UEFI 设置；然后确定 issue 中所示的其他模板设置在哪里处理。对于受影响的模板，所有模板设置都会以类似的异常被拒绝，同时未受影响的模板仍然可以添加设置时，此更改即完成。
