Add option to install Botkube via CLI, add --verbose flag

[mszostok]

Description

Changes proposed in this pull request:

• Add option to install Botkube via CLI
  - use Helm Go SDK underneath to install the chart
  - make sure it can be run with debug/verbose
  - support dry-run
  - support Botkube version and overrides
  - Respect KUBECONFIG env variable
• Add --verbose flag
  • it supports also modes that can be used to print more details. For example, for GraphQL call, we can print requests/responses when --verbose=trace is used. It should be useful to print it only if needed, as printing that all the time could be too messy.

Testing

1. Build the CLI
2. Create k8s cluster
3. Run:

export SLACK_CHANNEL_NAME=random
export SLACK_APP_TOKEN="xapp-1-"
export SLACK_BOT_TOKEN="xoxb-"

botkube install --verbose \
--set communications.default-group.socketSlack.enabled=true \
--set communications.default-group.socketSlack.channels.default.name=${SLACK_CHANNEL_NAME} \
--set communications.default-group.socketSlack.appToken=${SLACK_API_APP_TOKEN} \
--set communications.default-group.socketSlack.botToken=${SLACK_API_BOT_TOKEN} \
--set settings.clusterName=labs \
--set 'executors.k8s-default-tools.botkube/kubectl.enabled'=true \
--set 'executors.k8s-default-tools.botkube/helm.enabled'=true
