The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.

These tests reduce the server lock wait timeout which can increase
flakiness on loaded machines. Since this is merely an optimization,
eliminate them in favour of reliability.

These are ones likely to fail on heavily-loaded machines that alter the
normal test timing. Most of these tests already had the flaky keyword
since this condition makes them more likely to fail on CI.
These tests are run in SLOWDOWN mode which adds a 10 msec delay after
each character output, which means it takes at least 1.6 seconds (and
320 kernel calls) just to get through the long welcome banner. On an
overloaded system, this can end up taking much more than 1.6 seconds,
and even more than the 7 or 16 second curl timeout that the tests rely
on, causing them to fail. Reducing the size of the welcome banner drops
the total number of characters sent before the transfer starts by more
than half, which reduces the opportunity for test-breaking slowdowns by
the same amount.
Ref: #11328
As someone reported on the mailing list a while back, the hard-coded
arbitrary timeout of 7s in test 1112 is not sufficient in some build
environments. At Arista Networks we build and test curl as part of our
automated build system, and we've run into this timeout 170 times so
far. Our build servers are typically quite busy building and testing a
lot of code in parallel, so despite being beefy machines with 32 cores
and 128GB of RAM we still hit this 7s timeout regularly.
