Issue

ipa-client-install uninstall always tries to remove /etc/ipa/ca.crt irrespective what is name of ca file present in /etc/ipa or other path.

Steps to Reproduce

# ipa-client-install --ca-cert-file=/root/MyRootCA.pem
........
Continue to configure the system with these values? [no]: yes
User authorized to enroll computers: admin
Password for admin@<>: GIVE WRONG PASSWORD HERE
Installation failed. Rolling back changes.
The ipa-client-install command failed. See /var/log/ipaclient-install.log for more information

Why this happens is:
uninstall() function always deletes hardcoded value. Rather it should search for file present in path provided in --ca-cert-file option.
./ipaplatform/base/paths.py
IPA_CA_CRT = "/etc/ipa/ca.crt"
./ipaclient/install/client.py
remove_file(paths.IPA_CA_CRT)

Actual behavior

ca cert file named other than /etc/ipa/ca.crt is not removed.

Expected behavior

ca cert file what ever is provided in --ca-cert-file option should be removed.
