As a user, I can remove Tests from Test Sets / Test Executions / Pre-Conditions in Bulk

Currently in order to remove several tests from a Test Set or a Test Execution, each test must be removed manually.

A use case happens whenever we have a big Test Set and, for some reason we must remove a set of tests, for example the slow ones.

Xray must provide an option for removing Tests in bulk on the Test Set and Test Execution view issues screens. This option consists of a button located in the header in the operations column.

The Tests table should enter in bulk edit after the user presses a button and all Test entries must include a checkbox for selecting them. Also, the bulk operations menu trigger should appear with all the available bulk actions, in this case, removal. This trigger is a gear icon that must apear in the operations column header.

The selected rows should be highlighted with a different color.
