Issue:
[FEATURE] It might be a good idea to add a CONTRIBUTION file and a CODE_OF_CONDUCT
**Is your feature request related to a problem? Please describe.**
I'd like to contribute with the code of `dblab`, but I don't know very well `golang`

**Describe the solution you'd like**
Maybe could be a good idea to add a `CONTRIBUTING` file for new contributors to get some context of the project and for the environment setup, also could be a good idea to add a `CODE_OF_CONDUCT` to the repo, for the interaction between developers

**Describe alternatives you've considered**
I tried to run the code after I cloned, but I got an error `Error: empty values required to open a session in database`, 
I'm using `Goland`, then I noticed that I'm running the app without parameters so when I added `--help`, the error disappear



Pull request description:
feat(form): add a package to use a little tui to ask for the connection params to create a connection with database
# run dblab with no flags or parameters

## Description

Right now, dblab can not be launched with no parameters. So, I include a little tui to ask for the connection data.
