Expose lexer item types (#5358) * Expose lexer item types We have generally agreed to expose AST types / values that are necessary to make sense of the AST outside of the promql package. Currently the `UnaryExpr`, `BinaryExpr`, and `AggregateExpr` AST nodes store the lexer item type to indicate the operator type, but since the individual item types aren't exposed, an external user of the package cannot determine the operator type. So this PR exposes them. Although not all item types are required to make sense of the AST (some are really only used in the lexer), I decided to expose them all here to be somewhat more consistent. Another option would be to not use lexer item types at all in AST nodes. The concrete motivation is my work on the PromQL->Flux transpiler, but this ought to be useful for other cases as well.

promql: Add 'bool' modifier to comparison functions When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.

Expose lexer item types (#5358) * Expose lexer item types We have generally agreed to expose AST types / values that are necessary to make sense of the AST outside of the promql package. Currently the `UnaryExpr`, `BinaryExpr`, and `AggregateExpr` AST nodes store the lexer item type to indicate the operator type, but since the individual item types aren't exposed, an external user of the package cannot determine the operator type.

After this change all comparisons without 'bool' will filter, and all comparisons with 'bool' will return 0/1. This makes the language more consistent and orthogonal, and ultimately easier to learn and use. If we ever figure out sane semantics for filtering scalar/scalar comparisons we can add them in, which will most likely come out of how the new vector() function is used.

A use case is to return all metrics for nodes which do not have a specific role: node_load1 unless on(instance) chef_role{role="app"}

Currently the `UnaryExpr`, `BinaryExpr`, and `AggregateExpr` AST nodes store the lexer item type to indicate the operator type, but since the individual item types aren't exposed, an external user of the package cannot determine the operator type. So this PR exposes them. Although not all item types are required to make sense of the AST (some are really only used in the lexer), I decided to expose them all here to be somewhat more consistent. Another option would be to not use lexer item types at all in AST nodes. The concrete motivation is my work on the PromQL->Flux transpiler, but this ought to be useful for other cases as well.

promql: Add 'bool' modifier to comparison functions When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.

Fix parsing of label names which are also keywords The current separation between lexer and parser is a bit fuzzy when it comes to operators, aggregators and other keywords. The lexer already tries to determine the type of a token, even though that type might change depending on the context. This led to the problematic behavior that no tokens known to the lexer could be used as label names, including operators (and, by, ...), aggregators (count, quantile, ...) or other keywords (for, offset, ...). This change additionally checks whether an identifier is one of these types. We might want to check whether the specific item identification should be moved from the lexer to the parser.

Deprecate `keeping_extra`, rename it to `keep_common`. `keep_common` is more in line with the function name `drop_common_labels()` terminology-wise, and also more in line with `group_left`/`group_right` (no `...ing` verb suffix). We could also go the full way and call it `keep_common_labels`. That would have the benefit of being even more consistent with the function `drop_common_labels()` and would be more explanatory, but it also seems quite long.

Add without aggregator modifier. This has the advantage that the user doesn't need to list all labels they want to keep (as with "by") but without having to worry about inconsistent labels as when there's only one time series (as with "keeping_common"). Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".

Support escape sequences in strings and add raw strings. This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly.
