IRULE for HTTP HEADER STRING find and replace

If you are having a problem using this module, once you have instantiated object 't' in the example I found it useful to set the debug attribute to True as this allows for feedback on the installAS3 method when it's called e.g.:

>>> t.debug=True
>>> t.installAS3(host='BIGIP',username='SOME_USER',password='SOME_PASSWORD',filename='f5-appsvcs-3.17.1-1.noarch.rpm')
DEBUG: Filename f5-appsvcs-3.17.1-1.noarch.rpm specified, uploading to host BIGIP
DEBUG: Uploading file f5-appsvcs-3.17.1-1.noarch.rpm
DEBUG: Installing package f5-appsvcs-3.17.1-1.noarch.rpm from /var/config/rest/downloads
DEBUG: Created task to install package f5-appsvcs-3.17.1-1.noarch.rpm
DEBUG: Waiting for 5 secs
DEBUG: Checking whether the package is installed
DEBUG: Response from /mgmt/shared/appsvcs/info False
False
>>>

I also found in the imports in the module itself, that on my system (and I did do this in a virtual environment as well), I needed to amend the import statements as follows

#replaced import iCR
from iCR import iCR

I found when I used it, that the module was not referring to the iCR class correctly, and it needed the above in order to work without throwing an exception regarding the module not being callable.

HTH but still got a couple of snags left 😞 but looks very, very, useful when working so I am persevering with this. (note I am using python3.6.0)

If this is open sourced I can try and make this work on my system and submit a pull request with more detail if that is helpful.
