Add sqlboiler bazel rules

This implements a bazel rule to build sqlboiler models from sql migration stacks. It also launches a cockroachdb container in `create_container` and puts it in one pod with the nexantic-dev container.

Currently gazelle overwrites the `go_library` rule. I still need to find a way to properly exclude it.

Test Plan: Built a sample set of sql models

+##SQLboiler
+
+This rule allows to generate sqlboiler models and ORM code for golang from a stack of SQL migrations.
+
+It uses `sql-migrate`, `sqlboiler` and `sqlboiker-crdb`.
+
+###How to use
+
+Create a package and create a `0_initial.sql` file with the following template:
+
+```
+-- +migrate Up
+
+Your initial SQL goes here
+
+-- +migrate Down
+
+```
+
+Then create a `BUILD` file with the following rules:
+
+```
+load("//build/sqlboiler:sqlboiler.bzl", "go_sqlboiler_library", "sqlboiler")
+load("@io_bazel_rules_go//go:def.bzl", "go_library")
+
+# gazelle:ignore .
+
+sqlboiler(
+    name = "sqlboiler",
+    srcs = glob(["*.sql"]),
+    tables = [
+        <your table names>
+    ],
+)
+
+go_sqlboiler_library(
+    name = "sqlboiler_lib",
+    importpath = "git.monogon.dev/source/nexantic.git/<target>",
+    sqlboiler = ":sqlboiler",
+)
+
+go_library(
+    name = "go_default_library",
+    embed = [":sqlboiler_lib"],
+    importpath = "git.monogon.dev/source/nexantic.git/<target>",
+    visibility = ["//visibility:public"],
+)
+
+```
+
+Replace `target` with your intended importpath and add all created tables to the `tables` argument of the sqlboiler rule.
+
+Running the tasks will apply the migrations to a temporary database using `sql-migrate` and generate sqlboiler code from it.
+The code will be importable from the specified `importpath`.
+
+When making changes to the schema please generate new migrations using the `<n>_<description>.sql` pattern for file names.
+The migrations will automatically be applied and the models updated.
+
+Make sure to also update the `tables` argument when creating new tables in migrations.
