add integration tests to xcm-builder (#3537)

* add integration tests to xcm-builder * add an integration test for reserve_transfer_assets * add query holding and teleport tests * formatting * add to barrier doc comments and fix doc tests warnings * use more realistic barrier for integration tests * improve imports * adjust base xcm weight and existential deposit to be in line with Kusama * remove AnyNetwork Co-authored-by: Amar Singh <asinghchrony@protonmail.com> * add more comments and remove unnecessary code * move mock into separate file * reduce imports * update cargo.lock * remove reserve transfer test from xcm builder integration tests * reword barrier doc comment * elaborate on QueryHolding test scenario * add an integration test for reserve based transfers from parachain to parachain * add teleport tests * fix failing teleport filter tests * Update xcm/xcm-builder/src/integration_tests.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Update xcm/xcm-builder/src/integration_tests.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Update xcm/xcm-builder/src/integration_tests.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Move integration tests to tests/ directory * Fix merge * Replace All wildcard with a concrete seed amount * Rename SEED_AMOUNT to REGISTER_AMOUNT * Fix compilation error * Check for teleport destination first before checking out assets * Fix unit test * Do not run tests in integration mock * Add a permissive assets filter for teleportation * Remove check for teleport location in InitiateTeleport XCM * Remove defunct test * Apply suggestions from code review Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Reword comment Co-authored-by: Amar Singh <asinghchrony@protonmail.com> Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> Co-authored-by: Keith Yeung <kungfukeith11@gmail.com>
