chore: rename flexfun package

- FlexFunctions are now FlexConnect
- We will discontinue the old gooddata-flexfun and instead use gooddata-flexconnect
- Renamed everything accordingly
- There should be no sight of FlexFun anywhere now

+# GoodData FlexConnect
+
+GoodData FlexConnect allows you to build your own data source for GoodData Cloud or Cloud Native.
+
+FlexConnect works with a concept similar to 'table functions' that you may already know
+from database technologies.
+
+-  To build your own data source, you implement one or more FlexConnect functions. The
+   functions compute and return tabular data - how they do it is completely up to you.
+-  The functions are hosted and invoked inside a FlexConnect server (which is included in this package).
+-  A running FlexConnect server can be added as a data source to your GoodData Cloud or GoodData Cloud Native.
+-  The functions available on FlexConnect server will be mapped to data sets within GoodData's Semantic Model
+   and from then on can be used during report computation.
+
+
+## Getting Started using the FlexConnect Template
+
+The easiest way to get started writing FlexConnect functions is to use [the template repository](https://github.com/gooddata/gooddata-flexconnect-template).
+It provides a simple example of a FlexConnect function that can be used as a starting point for your own FlexConnect functions with all the necessary infrastructure in place.
+It also has a README that explains how to get started with the template and some general tips on how to write FlexConnect functions.
+
+## Getting started using the FlexConnect package directly
+
+Install the package alongside the gooddata-flight-server using pip:
+
+```bash
+pip install gooddata-flight-server gooddata-flexconnect
+```
+
+Next, update the GoodData Flight Server configuration to load the FlexConnect functions.
+
+```toml
+[flexconnect]
+
+# specify one or more modules that contain your FlexConnect function implementations
+#
+functions = [
+    "flexconnect.your_function"
+]
+```
+
+Then when running the GoodData Flight Server, use the `--methods-provider` option to load the FlexConnect.
+For example:
+
+```bash
+#!/bin/bash
+
+SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )"
+SERVER_CMD="${SCRIPT_DIR}/.venv/bin/gooddata-flight-server"
+
+export PYTHONPATH="${SCRIPT_DIR}/src"
+export CONFIG_ENV="${1:-dev}"
+
+$SERVER_CMD start \
+              --methods-provider gooddata_flexconnect \
+              --config \
+                config/${CONFIG_ENV}.server.toml \
+                config/flexconnect.config.toml \
+              --logging-config config/default.logging.ini \
+              --dev-log
+```
