fix: use InstallableFlake type & methods 
Fixes #134

Use the `InstallableFlake` type in order to make use of it's `toValue`
method. This fixes the functor auto-call by including the work from
nixos/nix#6404.

Future work may make use of this object and its methods to employ the
flake based eval cache.

adisbladis b9836f2e06 Add parameter to force recursion (don't honour recurseIntoAttrs) 
This can be useful when you are not in control over your expressions.

My use case is evaluating a Hydra jobset.

Zhaofeng Li 9f64612215 Don't override evalSettings.pureEval unless necessary 
Other eval flags like `--pure-eval` may activate `evalSettings.pureEval`,
so let's avoid touching it if we don't have to.

adisbladis fec10f2cfc src/nix-eval-jobs.cc: Reformat with clang-format 2022-04-26 21:20:24 +12:00
adisbladis 61c9f4cfcc Replace internal attr string representation with an array 
This ensures correct handling of attrnames with a dot in them and will
not throw errors about illegal attrnames.

Additionally this escapes any attributes containing dots in the JSON
output and adds another field called `attrPath` which contains the
attribute path as a list.

Example output:
```
{
  "attr": "hello",
  "attrPath": [
    "hello"
  ],
  "drvPath": "/nix/store/n204jib73z55cp9s0rmw1c5v5q528j7v-hello-2.12.drv",
  "name": "hello-2.12",
  "outputs": {
    "out": "/nix/store/h59dfk7dwrn7d2csykh9z9xm2miqmrnz-hello-2.12"
  },
  "system": "x86_64-linux"
}
```

adisbladis c1bbb11c5d Add support for recurseForDerivations 
This will respect `recurseForDerivations` when iterating over attrsets.

Example expression:
``` nix
{ system ? builtins.currentSystem }:
{
  recurseForDerivations = true;

  # This should build as it's in the top-level attrset
  drvA = derivation {
    inherit system;
    name = "drvA";
    builder = ":";
  };

  dontRecurse = {
    # This shouldn't build as `recurseForDerivations = true;` is not set
    # recurseForDerivations = true;

    # This should not build
    drvB = derivation {
      inherit system;
      name = "drvA";
      builder = ":";
    };
  };

  recurse = {
    # This should build
    recurseForDerivations = true;

    # This should not build
    drvC = derivation {
      inherit system;
      name = "drvC";
      builder = ":";
    };
  };

}
```

Zhaofeng Li 6d61193286 Flush cout after each output line 
The default buffering behavior depends on whether the output is connected
to an interactive device. This causes output lines to be buffered in an
undesirable way when stdout is piped, which is how nix-eval-jobs is
normally used. Let's fix it by flushing stdout explicitly.

adisbladis 3268f3a6af Add flag to enable meta 
I removed meta from the output in 434376f8e1 with the intention of adding it back gated by a flag, but that never happened.

Adding meta is quite a substantial increase in output size and has some non-trivial performance impact at scale, so it's best to leave it as opt-in.

Remove outputs from JSON output 
The output of the evaluator should only include either the full
derivation (not yet implemented) or fields not directly accessible
from the drv such as meta.

Right now the output is a fairly arbitrary selection of fields.
