promql: Organize legacy tests into appropriate files (#7989)
* Separate tests into:
** Aggregators
** Functions
** Operators
** Selectors
* Remove simple files and place tests into other files.
* Eliminate some of the _over_time tests since there are already plenty of
  edge cases present in the functions.test file.

Relates to #740

change labelset comparison in promql engine to avoid false positive during detection of duplicates (#7058)
* Use go1.14 new hash/maphash to hash both RHS and LHS instead of XOR'ing
which has been resulting in hash collisions.

* Use separate string functions that don't use strconv just for engine
maps.

* Use a byte invalid separator instead of quoting and have a buffer
attached to EvalNodeHelper instead of using a global pool in the labels
package.

* Address more review comments, labels has a function that now builds a
byte slice without turning it into a string.

* Use two different non-ascii hex codes as byte separators between labels
and between sets of labels when building bytes of a Labels struct.

* We only need the 2nd byte invalid sep. at the beginning of a
labels.Bytes
