Add bank count validation

[ronakseth96]

• Added validation to ensure the bank-count does not exceed the available banks.
• Added info, that the API URL is already pre-configured for local mode.

Example o/p:

$ ./test-load.sh --mode local --bank-count 15
WARNING: You have selected more banks (15) than available (10).
Please reduce the --bank-count value to 10 or fewer for performing load test.

@ronakseth96 is this a temporary solution until we produce the 600 bank images?

@2byrds Yes, this is a temporary solution. Currently, we only have data for 10 banks, and we are gradually verifying and updating more. Until we have all 600 bank images, this setup will be in place to manage the test.
