Fixing regex for dirnames capitalized

[alvadorn]

What does this PR do?

• Fix regex on directory names capitalized

Like referenced on issue #19, the latest release of plis can't attach containers on directories which its name are capitalized, for example:

• BACK-END-3, docker-compose uses back-end-3 as namespace but the current regex looks for BACK-END-3

Hi @alvadorn ! Thanks for your interest in plis :)

For the sake of clarity and purpose of the variables used in this method, I propose the following changes to the code in your PR:

1: leave dirName as it was prior to this PR:

            dirName := filepath.Base(currentWorkdir)

2: Add a new variable containerName:

        containerName := strings.ToLower(dirName + "_" + serviceName)

3: Use containerName in the regexPattern: (My bad... rp stands for "Regex Pattern" here... will correct that in another PR!)

      rp := regexp.MustCompile("^" + containerName + "_\\d+") 

Thanks for your PR! I'll just use a Willem Dafoe gif 'cause it's soo damn friggin' cool:

Totally agreed with your review. Fix pushed.
