Allowing search by 'Specification attribute name' in specification attributes page (Admin area)

[qasas145]

#7545 i have added this feature by these steps

• update GetSpecificationAttributeGroupsAsync in the ISpecificationAttributeService.cs file to have this signature GetSpecificationAttributeGroupsAsync(int pageIndex = 0, int pageSize = int.MaxValue, string specificationName = "") and this is to enable search by group name which contains this specification attribute
• update GetSpecificationAttributesByGroupIdAsync to GetSpecificationAttributesByGroupIdAsync(int? specificationAttributeGroupId = null, string name = "") to enable searching by attribute name in the group
• update PrepareSpecificationAttributeGroupListModelAsync in the SpecificationAttributeModelFactory
• update List.cshtml to include search box
• update SpecificationAttributeSearchModel.cs to include add searchName property
• update SpecificationAttributeGroupSearchModel.cs to include specification attribute search property

So this will be the page

You can type the attribute name and it will fetch the attribute and the group of it , and if it has no group then it appear in the default group

And you don't have to click on the control icon to display the result attributes , but the child table of specification attributes will open auto, so that you will see the attribute result directly
