[FEATURE] Disable values starting with a space

[andrijapanicsb]

Copying the global setting value (or some other value from UI), adds space in front of the copied text, then when pasting I managed to have a template whose name starts with space....

@rhtyd @davidjumani can we have textinput to trim entered text while submitting the form?

[utchoang]

@rhtyd I think we need to trim text input after entered?

[davidjumani]

We can do it both ways, but it would be better to trim it during the submit, to reduce the code changes introduced

@andrijapanicsb it may cause unexpected results in some cases, what is somebody wants to put space in front/end of a string input? Does old UI trim the space too ? I'm tentatively pushing this to 1.1 as it's not a critical/blocker issue.

David checked and it's an issue at backend, fixing this in UI will still allow API to do this - so ideally the backend should trim the space. Note - in backend, all API requests are handled by a parameter utility that parses values to strings/ints/long/short etc there a fix can be implemented to trim for String input/API parameters cc @davidjumani

Fixed in the backend via apache/cloudstack#4311

Closing based on @davidjumani 's remark, the fix at backend needs to be cautious but will ultimately fix the issue for all kinds of client inputs (UI, API...)
