If `cfg.TargetLabel` is a template like `$1`, it won't match any labels,
so no point calling `lb.Del` with it.
Similarly if `target` is not a valid label name, it won't match any
labels, so don't call with that either.
The intention seems to have been that a blank _value_ would delete the
target, so change that code to use `target` instead of `cfg.TargetLabel`.

Thought this would be a nice check on the `Validate()` function, but
some of the test cases needed tweaking to pass.

For `Lowercase`, `KeepEqual`, etc., we do not expand a regexp, so
the target label name must not contain anything like `${1}`.
Also for the common case that the `Replace` target does not require any
template expansion, check that the entire string passes label name
validity rules.

In https://github.com/prometheus/prometheus/pull/13276 we started reusing float histogram objects to reduce allocations in PromQL.
That PR introduces a bug where histogram pointers gets copied to the beginning of the histograms slice,
but are still kept in the end of the slice. When a new histogram is read into the last element,
it can overwrite a previous element because the pointer is the same.
This commit fixes the issue by moving outdated points to the end of the slice
so that we don't end up with duplicate pointers in the same buffer. In other words,
the slice gets rotated so that old objects can get reused.

Calling `*armnetwork.InterfacesClient.Get()` doesn't work for Scale Set
VM NIC, because these use a different Resource ID format.
Use `*armnetwork.InterfacesClient.GetVirtualMachineScaleSetNetworkInterface()`
instead. This needs both the scale set name and the instance ID, so
add an `InstanceID` field to the `virtualMachine` struct. `InstanceID`
is empty for a VM that isn't a ScaleSetVM.

It's faster.
Note change to test - instead of requiring that the data structure is
identical to `EmptyPostings()`, check that calling `Next()` returns
false, which implies it was empty.
Also the check for context cancellation during initialization was
removed. Initialization should be a small portion of the work done
during merge, so it's not worth plumbing a context argument through.
