The curl argument `--data-urlencode` doesn't accept equal signs between
the arg and the value, but needs whitespace instead.

* PromQL: Use a sync.Pool for the generated parser structure

The generated PromQL parser allocates a struct about 4kb in size on every run.

This puts a high load on the garbage collector.

To reduce that load, a sync.Pool is used to recycle these structures.

On small queries this makes parsing 2-3 times faster.

* PromQL: Avoid lexer item copies and allocations
Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>

Signed-off-by: Daniel Swarbrick <daniel.swarbrick@cloud.ionos.com>

During the PromQL parser rewrite there was some logic put in place that allowed switching between the non generated and the generated parser. Since the parser is now fully generated this is not needed anymore.
