Whitespace not omitted in Horizon search query

[Rene Soto]

When searching for Instances on Horizon, the query yields zero results if there is a space at the beginning or the end.

Steps to reproduce:
1. Create instance named "test"
2. Go to Project->Compute->Instances or Admin->System Panel->Instances
3. Search for "test"
4. Search for "test " (with space at the end)
5. Search for " test" (with space at the beginning)

Actual Results:
-Searching for "test" will successfully display the desired instance.
-Searching for "test " yields zero results.
-Searching for " test" yields zero results.

Expected Results:
It would be expected for Horizon to filter out whitespace before and after a search query, especially since whitespace is filtered before and after the name field upon instance creation.

Screenshot is attached. Customer reported this issue in MOS 7.0 and I was able to reproduce it.

Add strip() to filter string in instances

admin/instances and project/instaces
have server filter field.
This field do not strip search string,
so attempt to search "test " will return
nothing. This patch fixes it.
