Support Range header end in lfs (#11314)
* Initial support of end Range header option in lfs
* Allow end range option to be unspecified
* Declare toByte for consistency
* Factor out content encoding tests from doLfs
This is so Range tests could still use doLfs but without repeating
not related tests
* Add Range header test
* implemented extraHeader
* parametrized expectedStatus
* Add more test cases of Range header
* Fix S1030: should use resp.Body.String()
* Add more tests for edge cases
* Fix tests
