Update CI jobs and generate TLS test certs on the fly to avoid outdated test certs

First release of the [Nordix fork](https://github.com/Nordix/eredis_cluster] in April, 2021.

Support of TLS introduced in Redis 6
Uses Nordix/eredis (TLS, error handling fixes)
Many Dialyzer corrections
Elvis code formatting
Optimizations
- Refresh slot mapping reuses existing connection when possible and don't refresh mapping when not needed, e.g. when a pool is busy
- Don't use an extra wrapper process around each eredis connection process
Containerized testing
Testing using simulated Redis cluster for corner cases such as ASK redirects
Added API functions:
- connect/2: Connect to init nodes, with options
- qa2/1: Query all nodes with re-attempts, returns [{Node, Result}, ...]
- qn/2: Query to specific Redis node
- q_noreply/1: Query a single Redis node but wont wait for its result
- load_script/1: Pre-load script to all Redis nodes
- scan/4: Perform a scan command on given Redis nodes
- disconnect/1: Disconnect from given Redis node
- get_all_pools/0: Get all pools (one for each Redis node in cluster)
- get_pool_by_command/1: Get which Redis pool that handles a given command
- get_pool_by_key/1: Get which Redis pool that handles a given key
- eredis_cluster_monitor:get_cluster_nodes/0: Get cluster nodes information list (CLUSTER NODES)
- eredis_cluster_monitor:get_cluster_slots/0: Get cluster slots information (CLUSTER SLOTS)
Changed behaviour:
- qa/1: Query all nodes, now with re-attempts
- transaction/2: The second argument can be a Redis node (pool) or a key, instead of only a key

This release from 2019 and older are releases of the original adrienmo/eredis_cluster.
