bash jobs unnecessary --params requirement

[dapineyro]

The following command cloudos bash job --workflow-name ubuntu --command "echo 'a' > txt.txt" --last fails with the following error:

ValueError: No --job-config, --nextflow_profile, --parameter or --example_parameters were specified,  please use at least one of these options.

There are two issues here:

1. The following code snippet is not correctly capturing the bash jobs (aka docker), as it always triggers the first if:

cloudos-cli/cloudos_cli/jobs/job.py

Lines 307 to 321 in e092582

	if (
	nextflow_profile is None and
	job_config is None and
	len(parameter) == 0 and
	len(example_parameters) == 0
	):
	raise ValueError('No --job-config, --nextflow_profile, --parameter or ' +
	'--example_parameters were specified,' +
	' please use at least one of these options.')
	if workflow_type == 'wdl' and job_config is None and len(parameter) == 0:
	raise ValueError('No --job-config or --parameter were provided. At least one of ' +
	'these are required for WDL workflows.')
	if workflow_type == 'docker' and len(parameter) == 0:
	raise ValueError('No --parameter were provided. At least one of ' +
	'these are required for bash workflows.')

2. Bash jobs can run without params in the platform, so the following check is not necessary:

cloudos-cli/cloudos_cli/jobs/job.py

Lines 319 to 321 in e092582

	if workflow_type == 'docker' and len(parameter) == 0:
	raise ValueError('No --parameter were provided. At least one of ' +
	'these are required for bash workflows.')
