Sample - host_search.py - Includes comments from hostname_file in output.csv

[David-M-Berry]

Describe the bug
When running host_search.py and including a file with hostnames, if there are comments, the script will attempt to query for hosts with the full comment included. Comments should instead be ignored.

To Reproduce

1. Ensure you have a text file available with comments in it.

test$ cat hosts.txt 
#ubuntu hosts

tester1-ubuntu

2. run host_search.py with the -f HOSTNAME_FILE, --hostname_file HOSTNAME_FILE option

python3 host_search.py -f hosts.txt

3. Observe the output.csv file as having the commented line as a hostname, and a host not found error:

test$ cat output.csv 
Hostname,CID,RFM,Last Seen,Landscape,Tag1,Tag2,Tag3,Tag4
tester1-ubuntu,<aid>,no,2023-05-28T17:54:40Z,FalconGroupingTags/devTest,
#ubuntu hosts,HOST NOT FOUND

Expected behavior
Comments in text files containing hostnames are useful for administrators, and should be ignored by the script.

Environment (please complete the following information):

• OS: Ubuntu 22.04
• Python: Python 3.10.12
• FalconPy: crowdstrike-falconpy (1.4.3)
